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

IterationEngine - Achieves target coherence through intelligent retries.
|

|

This module implements professional-grade iteration strategies to achieve
|

coherence scores >= 0.90 for sample selections. Never accepts sub-standard
|
||||
results - either achieves target or fails explicitly.

|

Usage:

try:
|
||||

|

- Iteration strategies with progressive relaxation
|

- Automatic failure analysis and recovery suggestions
