feat(ops): add an intake-anomaly repair script for operators

repair-intake-anomalies.ts reports duplicate live rows sharing a slot
anchor and intake rows whose taken time sits implausibly far from their
slot. Dry-run by default; --fix tombstones duplicate losers with the
same precedence the nightly dedup applies and recomputes the affected
compliance rollup days; implausible rows are only listed unless
--tombstone-implausible is passed explicitly. Runbook under docs/ops.
