Add kubernetes_cron_job_v1.job_hunter_refresh — Sundays 04:00 UTC, runs
`refresh --source ats --source hn --source levels_fyi`, which upserts roles/
comp AND appends the dated comp_snapshots/roles_snapshots series consumed by
`job-hunter analyze`. Mirrors the Deployment's alembic-migrate init container
so a refresh never runs against an un-migrated DB; concurrency Forbid,
backoff 1, 30m activeDeadline, KYVERNO_LIFECYCLE_V1 dns_config ignore.
Add docs/runbooks/job-hunter.md: ops (health checks, manual refresh, add an
ATS company / CDIO watch, secret bag + rotation, failure table, TF apply) and
analyst (the analyze report, query recipes, SQL trend queries against the
snapshot tables, interpretation caveats) sections.
