Bundle the self-contained yt-dlp onedir runtime to avoid per-request extraction latency, explicitly use bundled Deno, and guard the packaging layout. Also fix Add window menu/reset behavior and harden diagnostics and toast lifecycle handling.
- Replace tokio::process with tauri_plugin_shell sidecar API for native cross-compilation bundle execution.
- Implement non-blocking stdout/stderr multiplexing in yt-dlp spawn to prevent OS pipe buffer deadlocks.
- Refactor capabilities to restrict execution explicitly to sidecars instead of wildcards.
- Rename local binaries to strictly adhere to target-triple architecture suffixes.
- Drop manual get_binary_name path resolutions in favor of Tauri's externalBin bundler.
