v1.3.3

Maintenance release completing the F-Droid reproducible-build work. The app module now pins the same NDK (27.2.12479018) as the native core, so libencnative.so and libandroidx.graphics.path.so strip deterministically and no longer depend on which NDK the build environment defaults to. Combined with the R8 baseline-profile fix from 1.3.2, the build is now fully reproducible. No changes to features, encryption, or your data. Signed with the same key as previous releases (cert SHA-256 561ae7dd…e915).
