feat: Implement senior audio injection with 5 fallback methods
- Add _cmd_create_arrangement_audio_pattern with 5-method fallback chain - Method 1: track.insert_arrangement_clip() [Live 12+] - Method 2: track.create_audio_clip() [Live 11+] - Method 3: arrangement_clips.add_new_clip() [Live 12+] - Method 4: Session->duplicate_clip_to_arrangement [Legacy] - Method 5: Session->Recording [Universal] - Add _cmd_duplicate_clip_to_arrangement for session-to-arrangement workflow - Update skills documentation - Verified: 3 clips created at positions [0, 4, 8] in Arrangement View Closes: Audio injection in Arrangement View
