sprint-start: add step 9 (post-work lifecycle) — commit, push, review,
fix-comments loop, approve, then shutdown. Team stays alive until PR is
accepted. Step 8e updated to reference the new lifecycle.
pr-push: add step 9 (team awareness) — don't shut down agents after
pushing, suggest /pr-review next.
pr-review: add step 8 (post-review team actions) — cross-references
sprint-start step 9c for dispatching review comments to agents on
CHANGES_REQUESTED and shutdown on APPROVED.
