Subject: [PATCH] Make the Claude stop-check blocking with autofix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Move the Stop hook into .claude/hooks/check-on-stop.sh. On a failed
  `make check` it exits 2, which makes Claude Code block the stop and
  feed the check output back to the agent to fix, instead of only
  reporting it; a passing check exits 0 and lets the turn end.

* It re-runs until green — interrupt to break out, or guard on the
  hook input's stop_hook_active to cap it at one attempt.
