fix([issue-3182]): dispatch output hooks from recovery paths

[atomantic]

Summary

• route orphan cleanup and post-restart completion through the shared output-hook dispatcher
• persist an exactly-once marker and serialize same-agent dispatch races
• keep recovery payloads null while preserving the existing timeout bound and early-termination behavior

Test plan

• npm test -- --run services/agentFinalization.outputHooks.test.js services/agentFinalization.successCriteria.test.js services/agentManagement.test.js services/agentLifecycle.test.js services/agentImportCycles.test.js
• full non-DB suite attempted with MEMORY_BACKEND=file; unrelated installState worktree assertion failed before the remaining suite completed

Closes #3182
