gsxdsm 1a3230ff93 FN-9186: Bound no-progress self-healing requeues

Bound no-progress self-healing retries so persistent failures stop consuming agent sessions.

- Persist a three-attempt retry budget with exponential backoff and an idempotent terminal sentinel.
- Prevent restart and wedge recovery paths from reopening exhausted failures.
- Emit bounded retry and exhaustion audit events with regression coverage and operator documentation.
