fix: prevent AbortSignal listener memory leak

- Add abort listener cleanup in Query.close() to prevent memory leak
- Add abort listener cleanup in ControlDispatcher.shutdown()
- Remove AbortController recreation in Session.handleInterrupt()

This fixes the MaxListenersExceededWarning that occurred when:
- Creating 11+ Query instances in SDK/non-interactive mode
- Multiple user interrupts (Ctrl+C) in interactive mode
- Intensive control request scenarios
