ci: temporarily revert runners to public images to bootstrap custom image build

## Problem

Init container skips registration if `.runner` file exists on PVC:
```
test -f /data/.runner || forgejo-runner register ...
```

This means changing runner labels in `values.yaml` (e.g. the label image fix from PR #1) has **no effect** until PVCs are manually deleted — not GitOps-friendly.

## Fix

Always delete `.runner` and re-register on every pod start:
```
rm -f /data/.runner
forgejo-runner register --no-interactive ...
```

Labels now stay in sync with `values.yaml` automatically. ArgoCD syncs → pods restart → init re-registers with current labels.

## Files Changed

- `k8s/infra/forgejo-runner/templates/deployment.yaml` (init container logic)

## After Merge

ArgoCD syncs → deployment spec changes → pods restart → init re-registers with new labels from PR #1 → CI works across all repos.Reviewed-on: #2

+        run: docker image prune -a --force 2>&1 | tail -3 || true
+```
+
+### Anti-Patterns (DO NOT USE)
+
+- ❌ `container: image: golang:1.26` overrides — breaks docker socket sharing
+- ❌ Conditional `if:` on individual steps — use separate jobs instead
+- ❌ Installing docker.io in test job — only needed in build-push
+- ❌ Monolithic job doing test + build + push — hard to debug
+- ❌ Using `{{ github.sha }}` for image tag — use short commit SHA for readability
+
+### How It Works
+
+1. **PR to feature branch** → test job runs, build-push skipped, nothing pushed
+2. **Push to main** → test runs, build-push runs after test passes, image pushed
+3. Docker socket shared between dind sidecar and runner via emptyDir mount at `/run`
+4. `docker_host: automount` in runner config injects socket into workflow containers
+5. Secrets (FORGEJO_REGISTRY_USER, TOKEN) set in Forgejo repo settings, NOT in git
