feat(socket): add configurable maxListeners to prevent memory leaks

Based on RSocket's battle-tested configuration:

- Add maxWebSocketListeners config option (default: 20)
  - 8 base WS events + 10 dynamic listeners + 2 buffer slots
- Add maxSocketClientListeners config option (default: 50)
- Replace dangerous setMaxListeners(0) with configurable limits
- Add warning log if user explicitly sets limit to 0

BREAKING: Previous behavior used setMaxListeners(0) which removed
all limits. Now defaults to safe limits but can be overridden via config.
