"""Update Star Office UI state (for testing or agent-driven sync).

For automatic state sync from OpenClaw: add a rule in your agent SOUL.md or AGENTS.md:
  Before starting a task: run `python3 set_state.py writing "doing XYZ"`.
  After finishing: run `python3 set_state.py idle "ready"`.
The office UI reads state from the same state.json this script writes.
