Inspect and control the user's running local dev servers and processes via the `marina` CLI. Use when the user asks what's running locally, what's using a port, or to stop/restart/open a dev server or project — e.g. "what's running", "what's on :3000", "is the frontend up", "kill the API", "stop the client-portal project", "free up port 5432", "restart the worker". Requires the `marina` binary on PATH.
