- Split Phase 5 into two rounds of questions
- Round 1: core settings (mode, depth, parallel, git tracking)
- Round 2: workflow agents (researcher, plan checker, verifier)
- Add explainer table before workflow questions
- Include workflow section in config.json schema
- Note that /gsd:settings can update later
