fix(harness): replace dead /api/world/ws with configurable WS bridge

- Replace dead HTTP path with direct WebSocket connection to server.py
- Add ws_host and ws_port query-param config (defaults: localhost:8765)
- Remove duplicate initializeMemPalace() call in connectHermes()
- Follows L402_PORT pattern for environment configuration

Closes #694
