New docs/RESTORE_DRILL_ROUTINE.md introduces a three-stage model:
weekly freshness check, monthly/bimonthly mini-restores, quarterly
DR sanity check. Tracks confirmed mini-restores (Vaultwarden, Gitea,
Paperless 2026-05-07; Immich 2026-05-27) and rotates services by
quarter Q1-Q4. Includes ten-point DR sanity check and abort rules
that point at the drift runbook. No host schedule is created; the
existing ops/restore-tests/schedule.md now references this routine
as the source for quarterly assignment.
