Lex Christopherson fb0ba88428 feat(16-02): add planner -> checker verification loop to plan-phase ...

- Steps 1-7: Validate, parse, spawn planner (existing flow)
- Step 8: Spawn gsd-plan-checker with verification_context
- Step 9: Handle checker return (passed | issues)
- Step 10: Revision loop (max 3 iterations)
- Step 11: Present final status with verification outcome

User sees ping-pong between planner and checker in main context.
