fix: resume saved user messages after execution recovery (#13270)

Preserve verified native process-stop evidence and retry saved user messages through normal continuation admission after recovery cleanup. Show the current wait reason and serialize delivery so a saved message starts one fresh turn.

Validated with 410 focused tests, typecheck, build, token gates, all PR CI checks, and Greptile 5/5.
