gsxdsm 4315cd01c6 FN-6598: suppress stuck detection during verification

Treat bounded verification subprocesses as healthy activity so progressing tasks avoid false stuck-loop recovery.

- Bracket fn_run_verification commands with stuck-detector start/end signals.
- Suppress loop and no-progress churn while verification is active, with timeout-bounded cleanup.
- Add regression coverage for verification heartbeats, compact-and-resume recovery, and no-progress churn behavior.
- Document verification suppression in reliability guidance.
