0.2.2 Preview — Classic progress layout

Classic now matches the Idle Slayer installation/removal progress page: 126 px ring with percentage, preparation/files/verification card, 6 px progress bar and status line. Existing product artwork, other pages and the engine transaction API remain unchanged.

Four public NuGet packages and six Native AOT SDKs are included. Native build/install/installed-uninstall checks passed on Windows, macOS and Linux, x64 and arm64. Both languages/themes rendered; MusicWars additionally passed 27 lifecycle checks, an update from 0.2.1 and 16 progress-state renders.

Preview release. Archives include SHA256SUMS and validation.json.
