- Turn on minification for the release build and sign it with the debug key so it is
installable for testing (a public release would use a dedicated keystore).
- proguard-rules.pro keeps the reflection-heavy mail/auth stack: Jakarta/Angus Mail
(IMAP/SMTP providers resolved via reflection + service files) and AppAuth.
- Verified on the Android 17 emulator: the release APK builds with R8, installs, and
syncs mail over IMAP — confirming Angus Mail's provider resolution survives shrinking.
