ci(release): trigger APK build and GitHub release on version tags

- Fires on any tag matching v* pushed to the repo
- Builds release APK, renames it koshika-<version>.apk
- Creates GitHub release with auto-generated notes and APK attached
- Tags with a hyphen (e.g. v0.2.0-facelift) are marked as pre-release
