Release 1.21.0

Added

• Configurable save directory for Autofill-saved entries under Settings > Autofill

Fixed

• Autofill save directory is now validated instead of silently rewritten, preventing unexpected save locations
• Fast-unlock PINs are isolated per PGP identity so a PIN can unlock only the key it belongs to
• Android SDK 37 compatibility by replacing removed MODE_PRIVATE constant

Changed

• Refreshed Public Suffix List for improved Autofill browser detection
• Selective upstream reconciliation with agrahn/Android-Password-Store
• Updated dependencies: Gradle 9.7.1, AGP 9.3.2, BouncyCastle 1.85.2, OkHttp 5.5.0, CodeQL 4.37.9
