v3.74.116

Cut playback continuity release. Manual cuts keep the prepared Media3 timeline instead of resetting the decoder; stored player listeners attach during lazy creation; transport state follows actual playback; replay restarts from zero after timeline end. Also includes the expanded preview, live-playhead Cut, selected-clip Delete, silent autosave restore, and 30-minute suggestion snooze. Device-proven after a cut from 4 to 28 seconds; clean unit tests, lint, signed APKs, checksums, fingerprints, size budgets, distribution metadata, and 16 KB alignment verified.
