#21 feat: add compact split torrent workspace

Summary

The torrent library currently places the selected torrent below the table. Replace this with a compact list beside a persistent detail inspector, giving the list more width than the details on desktop and stacking the panels on smaller screens.

• Keep the existing compact header, automation and add actions, and original status icons with progress rings.
• Show destination paths in All torrents and allow searching by torrent name, destination name, or path.
• Adapt file priorities and file actions to the narrower inspector, preserving the existing detail tabs and torrent controls.

Validation

• bun run tscheck
• bun run fix
• bun run test — 233 tests passed
• bun run build — production web/server build
• bun run build:desktop
• bun run test:native and bun run test:background for UI/native changes
• Engine/lifecycle behavior exercised through public APIs with real peers in temporary directories
• Downloaded files preserved unless deletion is explicitly requested
• CHANGELOG.md updated under Unreleased
• No credentials or personal data included
• AI-assisted code reviewed by a human

Browser validation: 32 checks passed with real local demo torrents, covering selection, pause/resume, file priorities, search, filters, sorting, dialogs, and destination navigation. Layouts from 320 to 1440 px have no page overflow or browser runtime errors. Native packaging and manual native UI checks were not run.

Summary by cubic

Replaces the torrent table with a compact list beside a persistent detail inspector, giving the list more width than the details on desktop and stacking the panels on smaller screens.

Details

• In All torrents, rows show the destination, and search matches torrent names plus destination names and paths.
• File priorities, actions, and detail tabs are adapted to the narrower inspector, and useDetailActions now exposes pause/resume.
• Desktop update checks now read the manifest directly from the native layer, avoiding GitHub API rate limits, and update downloads show live progress in the sidebar and panel.
• The player gains audio/subtitle track menus and a seek feedback overlay; completed files are opened with file-caching.
• The catalog download test now waits for seeding status, since received bytes can reach 100% before verification and disk writes finish.

Summary by CodeRabbit

• New Features
  • Reworked the torrent library into a scrollable list showing status, location, progress, and transfer rate. Selecting a torrent opens its details alongside the list.
  • Added search across torrent names and download paths, plus single-selection status filters.
  • Torrent details now show transfer statistics, save location, file progress, and controls for pausing, resuming, or repairing.
  • Desktop update checks use the native updater when available.
  • Added custom audio and subtitle menus, keyboard seeking, and clearer seek feedback in the media player.
• Improvements
  • Update controls show download progress and refresh update status while downloading or restarting.
