refactor(orchestrator): restructure post-verification workflow as Step 4-6

- Unified verification (Step 1-3) and post-verification (Step 4-6) into continuous workflow
- Step 4: Immediate plan file marking after verification passes
- Step 5: Commit atomic unit
- Step 6: Proceed to next task
- Emphasized immediacy: 'RIGHT NOW - Do not delay'
- Applied to both boulder state and standalone reminder contexts
