- Implement scheduler hydration barrier to prevent premature triggers
- Track scheduler exact runs using keys to avoid false stops
- Use 'System Events' for accurate macOS automation permissions
- Prevent system-sleep via proper idle assertions
- Ensure download pauses use channel acknowledgements (PauseWithAck)
- Require Firelink ownership before replacing files in add/conflict UI
- Retain partial download assets when removing entries without deletion
- Clear progress state in store when downloads complete or pause to reduce churn
- Handle empty/invalid queue selections gracefully
- Created root-level ToastProvider and useToast hook
- Replaced scattered ad-hoc toast states with unified provider
- Updated Settings, Scheduler, Speed Limiter, App, and DownloadTable to use ToastContext
- Added variant support (success, info, warning, error) with distinct styling
- Refined toast animations and styling for modern aesthetics
- Adjusted auto-dismiss behavior to ignore actionable or important errors
- Add backendRegisteredIds and backendDispatchPromises for single dispatch enforcement
- Add detach_download_for_reconfigure to safely modify properties of active downloads
- Add applyProperties logic handling completed, failed, paused, and active queues
- Add extractValidDownloadUrls and fix multi-url paste handling
- Setup vitest and add useDownloadStore unit tests for backend registration lifecycle
- Strip password, cookies, and headers from download_queue before writing
to store.bin; secrets remain in-memory for the active session only.
- Move extension pairing token from PersistedSettings to the OS keychain,
rotating it on upgrade from versions that persisted it as plaintext.
- Add ignores_legacy_extension_pairing_token_field test to confirm serde
silently drops the old field so existing installs migrate cleanly.
- Document intentional retention of URLs (signed params are the download
source and cannot be redacted without breaking resume/retry).
This commit replaces the frontend-imperative download dispatcher with a centralized backend `QueueManager`. It acts as the sole concurrency gatekeeper using a single `tokio::sync::Semaphore` across all download paths (aria2 RPC, native HTTP, yt-dlp media).
Backend Changes:
- **queue**: Added `QueueManager` to manage an ordered `VecDeque` of tasks, semaphore permits, and retirement debt (CAS resize).
- **commands**: Replaced direct start commands with `enqueue_download`, `enqueue_many`, `move_in_queue`, and `remove_from_queue`.
- **ipc**: Exported `DownloadStateEvent` and `QueueDirection` to the frontend.
- **tests**: Added 11 integration tests covering idle-parking, idempotent releases, CAS underflow prevention, and gid-completion races.
Frontend Changes:
- **store**: Made `useDownloadStore` reactive to the backend via the `download-state` event.
- **store**: Removed `processQueue` and introduced `pendingOrder` to track the accurate sequence of queued items.
- **ui**: Updated `DownloadItem` with queue visuals (clock icon, position badge).
- **ui**: Added Move Up/Down controls to interact with the backend queue reordering API.
