fix(build): revert to one-file yt-dlp binary to bypass macOS Gatekeeper Library Validation

Gatekeeper enforces Library Validation and prevents `dlopen` of quarantined ad-hoc signed dynamic libraries on ARM64. Because the `_internal` folder was shipped inside the DMG, the user's system flagged it with the com.apple.quarantine attribute, causing the Python shared library to fail to load inside `yt-dlp`.

By reverting back to the single-file PyInstaller binary (which is now properly code-signable without corruption on macOS), PyInstaller extracts the `_internal` folder at runtime to `/var/folders/...`. These extracted files do not inherit the quarantine flag, allowing AMFI to successfully load them and completely bypassing the dlopen system policy rejection.

+## [0.7.1] - 2026-06-11
+
+### Fixes
+- Increased the `yt-dlp` metadata extraction timeout to 120 seconds to properly handle YouTube's new JavaScript Proof-of-Work bot protection challenges.
+- Improved the `AddDownloadsView` UI to display the exact underlying error message during extraction failures rather than a generic masked string.
+
+### Security Fixes
+- Addressed multiple vulnerabilities identified in the v0.7.0 security audit.
+- Moved `yt-dlp` credential passing from CLI arguments to secure temporary configuration files to prevent process list leakage.
+- Enforced strict `0o600` POSIX permissions on `aria2c` temporary configuration files to protect generated RPC secrets.
+- Replaced the unauthenticated local connection protocol with a secure HMAC-SHA256 signature validation.
+- Excluded sensitive properties like `rpcSecret` and `rpcPort` from `DownloadItem` serialization so they are never saved to disk in plaintext.
+- Mitigated SSRF (Server-Side Request Forgery) by strictly validating metadata fetch requests against private IP addresses and loopback ranges.
+- Prevented potential path traversal vulnerabilities by validating destination file URLs during duplicate resolution.
+- Sanitized custom HTTP headers to prevent CR/LF injection vectors.
+- Re-architected `aria2c` port-finding with POSIX sockets to eliminate a known race-condition window.
+- Applied rate-limiting and text length bounds to the custom `firelink://` scheme to mitigate DoS and injection attempts.
+
+### Fixes
+- Fixed a metadata extraction timeout when downloading from YouTube by preventing child processes from holding process pipes open.
+- Resolved an issue to correctly assign filenames for auto-captured downloads.
+- Restored the UUID fallback for token generation to prevent silent failures if secure random byte generation fails.
+- Hardened local API security by immediately rejecting requests if the expected pairing token is completely empty.
+- Implemented a thread-safe cleanup mechanism for temporary directories to resolve a concurrency race condition during engine cancellation.
+
+## [0.7.0] - 2026-06-11
+
+### New Features & Improvements
+- Complete UI modernization for the context menu, toolbar, download list, and sidebar to adhere strictly to Apple's Human Interface Guidelines (HIG).
+- Overhaul of the Settings panes including Site Logins, Engine, About, Locations, and Downloads for a unified, cleaner look.
+- Introduce an "Ask where to save" global configuration option for manual location picking per download.
+- Add "Stop Time" option to the Scheduler and unit picker for the global Speed Limiter.
+- Enhance the Integration pane with a visible step counter and an up-to-date status icon.
+- Optimize `yt-dlp` execution for noticeably faster media extraction speeds.
+- Defer Keychain access prompts and track executable modification dates for a more secure "priming" mechanism.
+
+### Fixes
+- Fix issues regarding proxy environment propagation into media download processes.
+- Resolve multiple critical bugs related to configuration storage and download stability.
+- Address multiple underlying issues identified during comprehensive code reviews to improve overall resilience.
+
+## [0.6.6] - 2026-06-10
+
+### New Features
+- Add cascading media format pickers with inline loading states during metadata extraction.
+- Redesign the Integration settings pane for a more modern experience.
+- Overhaul the built-in update checker UI to integrate seamlessly into the settings.
+
+### Improvements
+- Implement keychain permission priming to defer secure access until explicitly granted, preventing unexpected macOS prompts.
+- Optimize core UI components to significantly improve rendering performance and overall app stability.
+
+### Fixes
+- Fix layout and dynamic sizing bugs in the Add Downloads window.
+- Fix formatting inconsistencies in media options selection.
+- Fix toast notification rendering glitches.
+
+## [0.6.5] - 2026-06-09
+
+### Fixes
+- Fix GitHub Actions build failure caused by an ambiguous bundle format when attempting to codesign `yt-dlp`'s embedded PyInstaller `Python.framework`.

+                                    even if the postprocessing fails
+    --no-abort-on-error             Continue with next video on download errors;
+                                    e.g. to skip unavailable videos in a
+                                    playlist (default)
+    --abort-on-error                Abort downloading of further videos if an
+                                    error occurs (Alias: --no-ignore-errors)
+    --list-extractors               List all supported extractors and exit

+                                    extractors and exit
+    --use-extractors NAMES          Extractor names to use separated by commas.
+                                    You can also use regexes, "all", "default"
+                                    and "end" (end URL matching); e.g. --ies
+                                    "holodex.*,end,youtube". Prefix the name
+                                    with a "-" to exclude it, e.g. --ies
+                                    default,-generic. Use --list-extractors for
+                                    a list of extractor names. (Alias: --ies)
+    --default-search PREFIX         Use this prefix for unqualified URLs. E.g.
+                                    "gvsearch2:python" downloads two videos from
+                                    google videos for the search term "python".
+                                    Use the value "auto" to let yt-dlp guess
+                                    ("auto_warning" to emit a warning when
+                                    guessing). "error" just throws an error. The
+                                    default value "fixup_error" repairs broken
+                                    URLs, but emits an error if this is not

+                                    is found inside the system configuration
+                                    file, the user configuration is not loaded.
+                                    (Alias: --no-config)

+                                    (default). When given inside a configuration
+                                    file, ignore all previous --config-locations
+                                    defined in the current file
+    --config-locations PATH         Location of the main configuration file;
+                                    either the path to the config or its
+                                    containing directory ("-" for stdin). Can be
+                                    used multiple times and inside other
+                                    configuration files
+    --plugin-dirs DIR               Path to an additional directory to search
+                                    for plugins. This option can be used
+                                    multiple times to add multiple directories.
+                                    Use "default" to search the default plugin
+                                    directories (default)
+    --no-plugin-dirs                Clear plugin directories to search,
+                                    including defaults and those provided by
+                                    previous --plugin-dirs
+    --js-runtimes RUNTIME[:PATH]    Additional JavaScript runtime to enable,
+                                    with an optional location for the runtime
+                                    (either the path to the binary or its
+                                    containing directory). This option can be
+                                    used multiple times to enable multiple
+                                    runtimes. Supported runtimes are (in order
+                                    of priority, from highest to lowest): deno,
+                                    node, quickjs, bun. Only "deno" is enabled
+                                    by default. The highest priority runtime
+                                    that is both enabled and available will be
+                                    used. In order to use a lower priority
+                                    runtime when "deno" is available, --no-js-
+                                    runtimes needs to be passed before enabling
+                                    other runtimes
+    --no-js-runtimes                Clear JavaScript runtimes to enable,
+                                    including defaults and those provided by
+                                    previous --js-runtimes
+    --remote-components COMPONENT   Remote components to allow yt-dlp to fetch
+                                    when required. This option is currently not
+                                    needed if you are using an official
+                                    executable or have the requisite version of
+                                    the yt-dlp-ejs package installed. You can
+                                    use this option multiple times to allow
+                                    multiple components. Supported values:
+                                    ejs:npm (external JavaScript components from
+                                    npm), ejs:github (external JavaScript
+                                    components from yt-dlp-ejs GitHub). By
+                                    default, no remote components are allowed
+    --no-remote-components          Disallow fetching of all remote components,
+                                    including any previously allowed by
+                                    --remote-components or defaults.
+    --flat-playlist                 Do not extract a playlist's URL result
+                                    entries; some entry metadata may be missing
+                                    and downloading may be bypassed
+    --no-flat-playlist              Fully extract the videos of a playlist
+                                    (default)
+    --live-from-start               Download livestreams from the start.
+                                    Currently experimental and only supported
+                                    for YouTube, Twitch, and TVer
+    --no-live-from-start            Download livestreams from the current time
+                                    (default)
+    --wait-for-video MIN[-MAX]      Wait for scheduled streams to become
+                                    available. Pass the minimum number of
+                                    seconds (or range) to wait between retries
+    --no-wait-for-video             Do not wait for scheduled streams (default)
+    --mark-watched                  Mark videos watched (even with --simulate)
+    --no-mark-watched               Do not mark videos watched (default)
+    --color [STREAM:]POLICY         Whether to emit color codes in output,
+                                    optionally prefixed by the STREAM (stdout or
+                                    stderr) to apply the setting to. Can be one
+                                    of "always", "auto" (default), "never", or
+                                    "no_color" (use non color terminal
+                                    sequences). Use "auto-tty" or "no_color-tty"
+                                    to decide based on terminal support only.
+                                    Can be used multiple times
+    --compat-options OPTS           Options that can help keep compatibility
+                                    with youtube-dl or youtube-dlc
+                                    configurations by reverting some of the
+                                    changes made in yt-dlp. See "Differences in
+                                    default behavior" for details
+    --alias ALIASES OPTIONS         Create aliases for an option string. Unless
+                                    an alias starts with a dash "-", it is
+                                    prefixed with "--". Arguments are parsed
+                                    according to the Python string formatting
+                                    mini-language. E.g. --alias get-audio,-X "-S
+                                    aext:{0},abr -x --audio-format {0}" creates
+                                    options "--get-audio" and "-X" that takes an
+                                    argument (ARG0) and expands to "-S
+                                    aext:ARG0,abr -x --audio-format ARG0". All
+                                    defined aliases are listed in the --help
+                                    output. Alias options can trigger more
+                                    aliases; so be careful to avoid defining
+                                    recursive options. As a safety measure, each
+                                    alias may be triggered a maximum of 100
+                                    times. This option can be used multiple
+                                    times
+    -t, --preset-alias PRESET       Applies a predefined set of options. e.g.
+                                    --preset-alias mp3. The following presets
+                                    are available: mp3, aac, mp4, mkv, sleep.
+                                    See the "Preset Aliases" section at the end
+                                    for more info. This option can be used
+                                    multiple times
+
+  Network Options:
+    --proxy URL                     Use the specified HTTP/HTTPS/SOCKS proxy. To
+                                    enable SOCKS proxy, specify a proper scheme,
+                                    e.g. socks5://user:pass@127.0.0.1:1080/.
+                                    Pass in an empty string (--proxy "") for
+                                    direct connection
+    --socket-timeout SECONDS        Time to wait before giving up, in seconds

+                                    is not present, and "&" to check multiple
+                                    conditions. Use a "\" to escape "&" or
+                                    quotes if needed. If used multiple times,
+                                    the filter matches if at least one of the
+                                    conditions is met. E.g. --match-filters

+                                    conversion (default) (Alias: --convert-
+                                    subtitles)

+                                    (currently supported: jpg, png, webp). You
+                                    can specify multiple rules using similar
+                                    syntax as "--remux-video". Use "--convert-

+    --split-chapters                Split video into multiple files based on
+                                    internal chapters. The "chapter:" prefix can
+                                    be used with "--paths" and "--output" to set
+                                    the output filename for the split files. See
+                                    "OUTPUT TEMPLATE" for details
+    --no-split-chapters             Do not split video based on chapters

+                                    given regular expression. The syntax is the
+                                    same as --download-sections. This option can
+                                    be used multiple times
+    --no-remove-chapters            Do not remove any chapters from the file

+                                    downloading/splitting/removing sections.
+                                    This is slow due to needing a re-encode, but
+                                    the resulting video may have fewer artifacts
+                                    around the cuts
+    --no-force-keyframes-at-cuts    Do not force keyframes around the chapters
+                                    when cutting/splitting (default)

+                                    separated by a colon ":". ARGS are a
+                                    semicolon ";" delimited list of NAME=VALUE.
+                                    The "when" argument determines when the
+                                    postprocessor is invoked. It can be one of
+                                    "pre_process" (after video extraction),
+                                    "after_filter" (after video passes filter),

+                                    (after moving the video file to its final
+                                    location), "after_video" (after downloading
+                                    and processing all formats of a video), or
+                                    "playlist" (at end of playlist). This option
+                                    can be used multiple times to add different
+                                    postprocessors

+                                    chapter, all and default (=all). You can
+                                    prefix the category with a "-" to exclude
+                                    it. See [1] for descriptions of the
+                                    categories. E.g. --sponsorblock-mark

+                                    remove takes precedence. The syntax and
+                                    available categories are the same as for
+                                    --sponsorblock-mark except that "default"
+                                    refers to "all,-filler" and poi_highlight,
+                                    chapter are not available

+                                    to "[SponsorBlock]: %(category_names)l"
+    --no-sponsorblock               Disable both --sponsorblock-mark and
+                                    --sponsorblock-remove
+    --sponsorblock-api URL          SponsorBlock API location, defaults to
+                                    https://sponsor.ajay.app
