chore(ai): add smoke test script (agent)

- Added `scripts/agent/smoke-test.mjs` to verify key flows:
  - Infrastructure: Local Relay (ws://localhost:8899) and Web Server (http://localhost:3000).
  - Protocol: Login, Video Post, View Event, DM Send/Decrypt.
  - UI: Headless Browser (Playwright) screenshot.
- Utilizes `scripts/agent/simple-relay.mjs` for a lightweight relay.
- Uses `scripts/agent/setup-test-env.js` for Node.js polyfills.
- Generates artifacts in `artifacts/` (log, summary JSON, screenshot).
