DeepWave 1.0.0

Initial release. FOSS flavor APK (de.binauralbeats.app.foss), developer-signed for F-Droid reproducible-build verification (AllowedAPKSigningKeys: b0fe178efdc103235048baa333116b0fa43366ec2da053e42379745fa00dae1a; v2-signing only). Built from commit 0ac43f0 using registry.gitlab.com/fdroid/fdroidserver:buildserver-trixie + gradlew-fdroid, signed with 'apksigner sign --alignment-preserved true' (build-tools 35.0.0's apksigner otherwise force-replaces zip alignment padding, which breaks apksigcopier's reproducible-build comparison even when file content is identical).
