+# Runs:
+#   1. shellcheck (if installed) at --severity=error on the runner
+#   2. bash -n syntax check on the runner + this script
+#   3. node --check on the dashboard (if node installed)
+#   4. a live init/add/run --once cycle against a throwaway queue using a
+#      no-op engine stub (no real agent CLI is ever invoked)
+#
+# It uses its own temp AGENT_QUEUE_ROOT so it never touches a real queue.
+# Exit 0 = all good. Run it before every commit.
