feat(flows): add update_mcp_worker flow with git_status, force-recreate, and health check

- update_mcp_worker.yml: git_status -> git_fetch -> git_pull (all cwd=scrum4me-docker) -> docker_compose_build -> docker_compose_up_recreate -> wait_for_health_worker
- commands.yml.example: add docker_compose_up_recreate (--force-recreate) and wait_for_health_worker (polls /var/log/agent/current for 'pre-flight passed')

-#   1. Fetch remote refs
-#   2. Fast-forward pull (aborts if working tree is dirty)
-#   3. Rebuild the Docker image
-#   4. Recreate the container in detached mode
-#   5. Verify the container is running
+#   1. Show current git status (informational)

+#   4. Rebuild the Docker image
