Replaces the Deployment-based runner with a StatefulSet using a proper
Docker-in-Docker sidecar for improved isolation and state management.
Key changes:
- StatefulSet deployment for stable pod identity and persistent storage
- Docker-in-Docker init container (privileged) providing isolated Docker daemon
- Two persistent volumes: runner-data (1Gi) for config, docker-data (20Gi) for image cache
- Uses hcloud-volumes storage class for durability
- Each replica gets its own Docker daemon and image cache
This addresses the workflow failure where job containers (node:24-bookworm)
couldn't access Docker because the CLI was missing. The DinD sidecar provides
a complete Docker environment for all job containers.
Fixes: DEV-335

Create runner deployment with:
- ServiceAccount and RBAC for runner pod
- ConfigMap for runner configuration
- Deployment using code.forgejo.org/forgejo/runner:4.0.1
- Argo CD application for automated deployment
Note: Runner requires a sealed secret with registration token.
See apps/forgejo-runner/README.md for setup instructions.
