brainstorm

Explore the solution space when the path isn't obvious - invent options, stress-test them, pick one. Use for architecture decisions, design tradeoffs, and when the user asks 'how should I approach X?'. Default produces a decision brief; pass `--quick` for chat-only, `--deep` for multi-round adversarial debate with full design doc. Do not use when want is unconfirmed (vd:interview), when the user says 'grill me' (vd:interview --grill), or when the deciding will not fit one session (vd:interview --wayfinder).
