Goal

The durable run folder is removed on terminal completion and ONLY on terminal completion (it survives a non-terminal exit so resume works).

Implementation Sketch

Add a terminal-completion cleanup that removes .impl-hygiene-run/<run_id>/ when the run reaches its terminal phase (Phase 5 present / Phase 6 done). A non-terminal exit (mid-walk interruption) leaves the folder so §01 resume can pick it up.

Spec References

scripts/impl_hygiene_review_runtime/state.py (cleanup); CLAUDE.md §ZERO DEFERRAL (no temp accumulation).

Work Items

• Remove the durable run folder on terminal completion; leave it intact on a non-terminal exit.
• pytest: folder removed on terminal completion; folder survives a simulated non-terminal exit.
