feat: wire action-type CI into contributor profiles

- contribution_scores table stores per-PR CI with action type
- Profile endpoint returns action_ci alongside role-based ci_score
- Branch-name attribution: contrib/NAME/ PRs attributed to NAME
- Cameron now shows 0.32 CI + BELIEF MOVER badge from challenge
- Handle variant matching (cameron-s1 → cameron) for cross-system lookup
- Full historical backfill: 985 scores across 9 contributors
