gsd-orchestrator

<mental_model> GSD headless is a subprocess you launch and monitor. Think of it like a junior developer you hand a spec to:

1. You write the spec (what to build)
2. You launch the build (gsd headless ... new-milestone --context spec.md --auto)
3. You wait for it to finish (exit code tells you the outcome)
4. You check the result (query state, inspect files, verify deliverables)
5. If blocked, you intervene (steer, supply answers, or escalate)

The subprocess handles all planning, coding, testing, and git commits internally. You never write application code yourself — GSD does that. </mental_model>
