Merge remote-tracking branch 'origin/develop' into refactor/js-to-ts-migration

refactor: migrate JS/MJS sources and scripts to TypeScript
Migrate all remaining migratable .js/.mjs files to .ts with strong typing: - constants/MediaTypes: as const + derived MediaType union - utils/profiles/{download,subtitles,trackplayer}: typed against @jellyfin/sdk DeviceProfile/SubtitleProfile/CodecProfile models; native.ts now validates its profile with `satisfies DeviceProfile` - trackplayer.d.ts removed (superseded by real TS implementation) - index.js -> index.ts (entry point, "main" is extension-less) - scripts/{typecheck,check-i18n-keys,detect-duplicate-issue} -> .ts, all run via bun (typecheck switched from node to bun) Remove scripts/symlink-native-dirs.js: dead since 446439c2 (2025-02-28) when its only reference (prebuild:tv-new) was dropped; superseded by `expo prebuild --clean` + cross-env EXPO_TV. Drop the matching .gitignore relics (/iostv, /iosmobile, /androidmobile, /androidtv). Document tooling-required .js exceptions (babel/metro/react-native/ tailwind configs) in CLAUDE.md and copilot-instructions.md so code review guidelines stop flagging them.
