collatz: formalize universal D/F clauses and report all C2 transitions
**Motivations:**
- Convert observed witnesses into universal clause statements usable in well-founded induction
- Ensure c2_projective run report reflects every discovered transition
**Root causes:**
- H4/H5 universality bridge was implicit
- c2_projective run report only displayed legacy checks (m14→m16)
**Correctifs:**
- Add explicit universal D/F clause forms, thresholds, and induction closure schema
- Extend c2_projective metrics rendering to iterate over verification JSON transitions
**Evolutions:**
- None
