Test Suite: Live World-Change Responsiveness & Process Kill/Restart Recovery
===========================================================================
Validates:
1. External Mutation Detection: Daemon detects a real physical file change mid-run.
2. Kill -> Restart Recovery: Resumes seamlessly from disk checkpoint without state loss.
