feat: Electron desktop app, native ffmpeg export, fully static web

- apps/desktop: Electron shell serving the static web build over a
  privileged opencut:// protocol; exports stream frames over IPC to a
  bundled ffmpeg (libx264/libvpx-vp9, BT.709 tagged) with backpressure.
  electron-builder packaging: AppImage, deb, rpm.
- apps/web: dead backend deleted (better-auth, drizzle/pg, upstash,
  botid, freesound proxy, blog, rss, env validation); next build emits
  a zero-env static export; /editor/[project_id] -> /editor?project=.
- Native exporter mirrors SceneExporter; activates when the preload
  bridge is present; web keeps the mediabunny path.
- Docker self-hosting now builds and serves the static export via nginx.
- Release workflow: v* tags publish static web tarball + Linux packages.
- Changelog 0.4.0; README/AGENTS/CONTRIBUTING/roadmap updated.
- GPUI/Rust rewrite parked on branch rust-rewrite.
