Change runner from runners-farhoodlabs to ubuntu-latest across all fork
workflows. Update container registry from ghcr.io to git.farh.net and
authenticate with REGISTRY_TOKEN. Migrate update-infra API calls from
GitHub to Gitea. Disable refresh-lockfile.yml (requires GitHub gh CLI).
Update CLAUDE.md references.

The self-hosted runner has been hitting context-deadline timeouts to
docker.io. The actual image push goes to GHCR, so the Docker Hub login
is only there to avoid pull rate limits. Mark it continue-on-error so
transient docker.io connectivity issues don't fail the whole build —
base image pulls fall back to anonymous and proceed.
