v1.4.2

Added

• Notification-triggered-overlay count telemetry in the debug panel (inferential proxy to separate genuine AOD-on time from this app's own activity).
• Debug builds now show a git-hash build identifier in the version string.
• New verifyReleaseSigning Gradle task - fails the build loudly if the release APK isn't signed with the expected certificate.

Fixed

• Resolved all lint build errors (invalid protected-permission declaration; android:tint -> app:tint).
