Fix connect accumulation; add display sinks to enum-devices

Browse Source 
- controller_cli: drain semaphore and reset pending_cmd in do_connect
  so stale posts from old connection don't unblock the next command
- protocol: add Proto_Display_Device_Info; extend
  proto_write_enum_devices_response and proto_read_enum_devices_response
  with display section; backward-compatible (absent in older messages)
- node: handle_enum_devices snapshots active Display_Slots under mutex
  and includes them in the response
- controller_cli: on_display callback prints display window info in
  enum-devices output
- query_cli: updated to pass NULL on_display (no display interest)
