feat(ogagent): report busy state and os type in heartbeat ping

Add 'busy' and 'st' fields to the periodic webhook ping so ogCore can
track whether a client is executing a job without waiting for a command
response.

- oglive_worker: busy derived from thread_list running state, st='OGL'
- OpenGnSys module: busy derived from jobmgr active processes, st mapped
  from operations.os_type (LNX/WIN/OSX)
