feat(ask): split question artifact path from proposal path

Adds dedicated ContemplationResult.question_path for off-serving ASK artifacts and stops storing QUESTION_NEEDED question paths in proposal_path. Proposal artifacts remain under proposal_path. No chat/runtime wiring, served ASK surface, Q1B carve-out retirement, registry flip, or CLAIMS/metric movement.
