Subject: Main-screen recordings list, player actions, background recording,
 exports (1.4.0-alpha)

- Main screen: recordings list at the bottom (newest first); removed the separate
  library screen and the top-right link
- Player: delete/rename/share/export, no autoplay, embedded-marker fallback
- Word-level tap-to-seek from Whisper token timestamps (length fallback)
- Export transcripts as .txt + .srt to Downloads
- RecordingService: microphone foreground service for background recording
- FileProvider for sharing on Android 9 and older
- StreamingResampler extracted to its own class + JUnit regression tests
- Bump to 1.4.0-alpha (versionCode 6)
