Add skip01 NixOS configuration for Intel NUC server

- Created systems/skip01.nix with 13th gen Intel i5 NUC optimizations
- Configured for headless server operation with SSH access
- Enabled Docker and Podman for container services
- Added Intel graphics support and thermal management
- Network performance tuning for server workloads
- Added skip01 to flake.nix nixosConfigurations
