roles: add role-based host composition in flake

- mkHost now takes a role list, roles resolve to ./roles/<name>.nix
- roles/core.nix = shared baseline (modules/)
- roles/k3s-server.nix = core + k3s (goyplex-vm)
- roles/hermes.nix = core + hermes (hermes-vm)
- host configuration.nix trimmed to hardware + boot + stateVersion
- optional hosts/<name>/custom.nix loads last for per-host overrides
- new hosts: one flake line + hosts/<name>/ dir
