agent afed70586a fix: add git-daemon so git-http-backend exists in the image

Alpine splits git-http-backend OUT of the `git` package: git alone ships
git-remote-http/https but not the CGI backend. The runner therefore had git
2.52.0 and no git-http-backend, so zegit's internal/forgeprobe smart-HTTP tests
failed at request time with "fork/exec git-http-backend: no such file or
directory" and reported three FAILURES for a missing tool.

That turned Gitea CI red on every zegit master commit while GitHub stayed
green, for hours, with nobody looking — GitHub is the release oracle, which is
exactly why a red mirror is invisible.

Verified against the real base image, not just alpine:3 — on
code.forgejo.org/forgejo/runner:12.11.1 (Alpine 3.23), `apk add git git-daemon`
puts git-http-backend at /usr/libexec/git-core/git-http-backend, and
`git --exec-path` resolves to that directory, which is the lookup the test
harness performs.

feat: custom toolchain image for host-mode Gitea Actions runner

zegit-forgejo-runner

Custom toolchain image for the cluster's self-hosted Gitea Actions (Forgejo) runner, which runs in host mode (Docker disabled) — workflow steps execute inside this image, so it must carry node/git/make/etc. that the stock code.forgejo.org/forgejo/runner image lacks.

This repo lives only on Gitea (zegit-zoo/zegit-forgejo-runner). The cluster-side deployment and rationale live in flux-config (runners.md, applications/forgejo-runner/).

Build & push

The runner needs this image to run any job, so the first build must be done by hand (CI can't bootstrap itself). The cluster is mixed amd64/arm64, so build multi-arch:

docker buildx create --use --name zegit-ci 2>/dev/null || true
docker login gitea.langenoja.se        # username + a Gitea personal access token
docker buildx build --platform linux/amd64,linux/arm64 \
  -t gitea.langenoja.se/zegit-zoo/zegit-forgejo-runner:12.11.1-ci --push .

The Gitea package is public, so the forgejo-runner-system namespace pulls it without an imagePullSecret.

Wire it into the cluster

After the push succeeds, in flux-config applications/forgejo-runner/base/deployment-forgejo-runner.yaml set the image: on both the register initContainer and the forgejo-runner daemon to gitea.langenoja.se/zegit-zoo/zegit-forgejo-runner:12.11.1-ci, then commit (Flux reconciles). Do this only after the image exists, or the pod ImagePullBackOffs.

Tag scheme

<base-runner-version>-ci (e.g. 12.11.1-ci). Must satisfy the cluster's Gatekeeper enforce-semantic-image-tags constraint — never :latest.
