v0.2.0

Download System Rewrite

• New Rust-based download backend — Replaced the Python vid-dl CLI (~150MB) with a native Rust binary (desk-downloader). Smaller, faster, and no Python dependency at runtime.
• Rewrite download IPC layer — New desk-downloads.js / desk-downloader.js replacing the old downloads.js / downloader.js with a cleaner subprocess management and progress event architecture.

Bug Fixes

• Downloads freezing near completion — Root cause: main window reference was captured as null at registration time, silently dropping all sendProgress IPC calls. Fixed by passing getMainWindow function reference instead.
• Stop button not updating UI — stop/kill used 'stopped'/'killed' status values rejected by the DB CHECK constraint. Now maps to 'cancelled' for persistence.
• Progress bar stuck at 0% — Added mapping from pct (subprocess field) to progress (UI field) so the bar updates in real time.
• Download size fluctuating mid-download — First total_bytes value is now frozen; subsequent progress events no longer overwrite it.
• Stray "0" rendering beside speed — Fixed ternary rendering for speed display in DownloadsPage.jsx.
• Safety-net polling — Full fetchDownloads() refresh every 3 seconds catches any terminal state missed by live progress events.

UI Enhancements

• Download rows now show raw downloaded_bytes (comma-formatted) alongside formatted total_bytes.
• formatBytes precision changed from 1 to 2 decimal places.
• VidSrc downloads: visible browser window with play-button banner (no auto-clicking).
• Quick-download blocked for VidSrc (info message in DownloadModal).
• AllManga downloads blocked for non-anime content (info message in DownloadModal).
• PlayerSection download button requires video to be played first.

Chores

• Removed vid-dl-cli source repo and all prebuilt binaries (Linux + Windows) from tree.
• Added apps/desk-vid-dl/ Python package for on-the-fly PyInstaller builds.
• Updated README, ARCHITECTURE.md, sources config, and settings UI.
