Linthra 0.1.1 — now available on F-Droid.

Changed:
- Improved Chromecast battery behavior while paused: receiver polling now
  stops while paused/idle and resumes on play, cutting background CPU wake-ups.

Maintenance (no app behavior change):
- Added audit coverage for Bluetooth, BLE/LE Audio output, and CPU efficiency.
- Added F-Droid release guardrails (version code and release-asset checks).
- Cleaned up the release-process documentation.

No ads, no tracking, no analytics, no telemetry.
