docs: add question-gen v3 construction-paradigm design and phase1 plan

Complete v3 planning: construction-first paradigm (frame-perception grounded fact extraction + 4-family independent judges + 6-layer verification + QuestionUnit contract), adversarial audit, paradigm-shift finding, real-data spike validation, logging schema, and phase1 contract implementation plan.
