FN-7173: preserve stuck triage drafts on requeue
Stuck triage retries now continue from saved planning drafts instead of restarting.
- Detect non-empty PROMPT.md drafts or saved plan task documents after stuck-detector aborts.
- Requeue draft-backed stuck triage runs as replans with explicit resume feedback and bounded retry escalation.
- Cover prompt-vs-plan recovery, cold retries, approval recovery, and exhaustion behavior in engine tests.
- Document the stuck-triage preservation invariant and add a patch changeset.
