Subject: [PATCH] feat: add developer container config with packages/ mount

- docker-compose.yml for standalone Docker usage
- .devcontainer/devcontainer.json for VS Code/Cursor
- Mounts packages/ as /workspace in container
- Persists home directory with named volume
- SSH and gitconfig mounted read-only

Uses ghcr.io/host-uk/core-images/developer:latest
