Support both docker-compose and docker compose commands

- Auto-detect standalone docker-compose vs docker compose plugin
- Works on ZimaOS which uses docker compose (v2)
- Works on older systems with docker-compose (v1)
- Updated all script commands to use detected version
- Better error messages showing which version is being used
