Commodore ROMs are copyrighted and can no longer ship inside the APK. MainActivity now detects missing ROMs on first launch and blocks startup with a dialog offering two paths: pick files via the system file picker, or download the official VICE 3.8 tarball and extract the four ROMs from it client-side (minimal USTAR reader, no extra deps). - Drop the extractViceRoms Gradle task and asset bundling; add res/extract_roms.sh for local sideloading during development instead - gitignore keystores/keystore.properties ahead of a signed release - Move architecture.md into docs/, refresh it for the screen-mirroring and watch-input additions, and add accompanying Mermaid diagrams - Add docs/debugging.md and docs/publish.md (Play Store release notes, ROM-import compliance rationale)
