Add run_context to agent tool calls for FE run logging

- AgentTriggerRequest accepts optional agent_id (FE's stable electron-store UUID)
- _make_agent_executor injects run_context into every tool_call frame
  so Electron can attribute actions to the correct agent run
- run_local_agent accepts run_context and sends a run_complete WS frame
  when the run finishes so the FE can close the run record
- trigger_agent_run builds run_context with run_id=run_log.id and the
  stable agent_id, passes it through to run_local_agent
