Security Review ✅

• S0 (project scoping): N/A — the PR only renames the worker WebSocket path from /worker to /worker/socket in lib/lightning_web/endpoint.ex:23 and matches it in lib/lightning/runtime/runtime_manager.ex:108; no data queries changed.
• S1 (authorization): N/A — no new web-layer actions; WorkerSocket.connect/3 still gates on Workers.verify_worker_token/1 (lib/lightning_web/channels/worker_socket.ex:32), unchanged.
• S2 (audit trail): N/A — no config-resource writes introduced.
