Use fragment progress for HLS downloads, prevent false multi-track completion, require exact resolution matches, and remove the ambiguous Best format option and obsolete frontend parser.
Estimate missing stream sizes from bitrate and duration, bind displayed options to exact yt-dlp stream IDs, and propagate approximate totals consistently to download rows.
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.

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.
