Dedicated CI runner LXC for all repos

[rodaddy]

Summary

Create a dedicated LXC container as a shared GitHub Actions self-hosted runner for all repos (mcp2cli, king-ng, future projects).

Current State

• king-ng has a repo-level runner (king-ng-lxc) -- tied to that repo only
• mcp2cli has no runner -- Claude Code Review workflow needs one to reach LiteLLM

Proposed Setup

1. New LXC on Proxmox dedicated to CI
2. Install: Bun, Node.js, GitHub Actions runner agent
3. Register as repo-level runner for each project (personal accounts can't use org runners)
4. Labels: self-hosted, ci, plus project-specific labels as needed
5. Network access to LiteLLM (10.71.20.53:4000) for Claude review workflows
6. Secret LITELLM_API_KEY set on each repo that uses Claude review

Migration

• Move king-ng's runner from king-ng-lxc to the shared CI LXC
• Update workflow labels from king-ng to ci (or keep both as labels)

Depends On

• /deploy-service skill for LXC provisioning
