New endpoint replaces the legacy /api/contributors *_count read path with
event-sourced reads from the Phase A contribution_events ledger.
- Params: window (all_time | Nd | Nh), kind (person | agent | org | all),
domain (filter), limit (default 100, max 500)
- Returns per-handle CI, full role breakdown (author/challenger/synthesizer/
originator/evaluator), events_count, pr_count, first/last contribution
- ORDER BY ci DESC, last_contribution DESC — recent contributors break ties
- Read-only sqlite URI; total/has_more computed for paginated UIs
Wiring (import + register + _PUBLIC_PATHS entry) currently applied to live
app.py on VPS only — repo app.py has drift from Ship's uncommitted /api/search
POST contract. Next deploy.sh round-trip needs both to land together.
