A real native desktop app (egui window) whose entire decision logic is an operon program embedded via the language's own lib target (VM lane, capability sandbox). No localhost server, no browser, no Python. Ported Youwee features, all decided in op/app.op: - audio extraction with codec choice (mp3/m4a/opus) - subtitles: sidecar download and/or embed into the file - SponsorBlock removal (sponsor/intro/outro/selfpromo) - bandwidth limit via aria2 --max-overall-download-limit - playlist mode (drops --no-playlist on the download argv) - download library (history.json), settings persistence (settings.json) - six-theme accent system (name persisted operon-side) - deduped resolution-sorted format menu, [download] x% progress parsing Carried-over contract: aria2 is the ONLY bundled tool (embedded, extracted on first run); yt-dlp/ffmpeg come from the user's PATH (green/red dots); 30 MB size gate in CI; long children supervised by the host (operon run() containment caps children at 5 min by design) while every progress line still flows through the operon state machine. Gates: 6 unit tests (incl. youwee_options_shape_the_download_argv and defaults_stay_clean), cross-platform end-to-end flow regression with a fake yt-dlp, --smoke headless boot of the shipped exe, size gate. Pins operon-lang-dev @ c578b04 (main: P4 MapStore + P2 merge sort + P3 lazy range + P5 string-builder waves).

Adds
desktop-operon/: the Youwee downloader core ported to operon — a real native desktop window (egui) whose entire decision logic is an operon program. The Tauri application is untouched; this is a separate lane so upstream syncs stay trivial.Youwee features ported (all decided in operon, op/app.op)
