Cold-start bug surfaced germinating a grandchild + building an app on it: in-cluster DNS only rewrote git.<domain> / mcp.<domain> to Traefik, plus a stale exact app.shipits.app. App hostnames (<app>-<owner>.<domain>, pr-<n>-...) did NOT resolve in-cluster, so the agents reviewer/builder could not browse an app preview/prod and review silently failed.

This makes germinate WRITE coredns-custom per-domain as a single regex rewrite ((.*)\.<domain> -> Traefik) covering git, mcp, and every app. We own the file rather than leaning on rewrite_identity_domain, because that sed escapes dots and cannot re-domain an escaped-dot regex, and it skips the stale app.shipits.app (not the seed domain).

Validated on a live grandchild: before, in-cluster nslookup <app>.<domain> returned no answer and the agents pod could not reach the app; after, all hostnames resolve to Traefik and the agents pod gets HTTP 200 from the app.
