feat: add Docker deployment, update install script, and project configs

- Add Dockerfile and docker-compose.yml for containerized deployment
- Rewrite install.sh for Docker-based setup (multi-distro support)
- Add Go module files (go.mod, go.sum) for WGRplane backend
- Add wgrplane.service systemd unit for Go backend
- Add CI verification scripts in scripts/
- Update README.md with Docker deployment docs
- Update .gitignore for binaries and .sisyphus/
