Viktor Barzin b6976ce014 forgejo pulls: pin registry name to internal Traefik in node /etc/hosts [ci skip] 
tuya-bridge was down 7.5h (ImagePullBackOff on k8s-node3): fresh kubelet
pulls of forgejo.viktorbarzin.me images depended on the intermittently
broken public-IP hairpin. The containerd hosts.toml mirror cannot keep
pulls internal on its own — Traefik 404s its bare-IP requests (no
Host/SNI match) and the registry Bearer realm is an absolute public URL
fetched outside the mirror. Third incident of this class (buildkit
06-04, tripit/devvm 06-09).

Fix: /etc/hosts pin 10.0.20.203 forgejo.viktorbarzin.me on every node —
covers resolve + token + blob legs with correct SNI and valid cert.
Applied live to all 7 nodes; persisted in the cloud-init bootstrap and
the existing-node rollout script. Docs updated (registry bullet, dns.md
hairpin scope + stale .200 literals, runbook) + post-mortem.
