feat: initialize repo with NixOS and Home Manager configs

- Add .gitignore for common languages, tools, and OS/editor artifacts
- Configure .gitattributes for Git LFS (fonts, images, archives, ISOs)
- Add README with repo description
- Add flake.nix defining inputs and outputs for NixOS, Home Manager, and related modules
- Introduce home-manager configs:
  - Base home.nix with packages, services, and programs
  - Hyprland WM configuration (waybar, fuzzel, keybindings, theming)
  - Vim (nixvim) setup with LSP and plugins
  - Zsh setup with aliases, Oh My Zsh, clipboard helpers
  - Systemd user services (e.g., librespot)
- Add scripts (GPU monitor, RAM build helper, install automation)
- Add host configurations:
  - Nixbook (Apple laptop) with hardware, disko, and install script
  - Nixstation (desktop) with firewall, virtualization, Btrfs scrub timer
  - Nixtest (test VM) with QEMU + Alpine-based install test harness
  - Common modules (network, NVIDIA, rclone, screen, keychron, users)
- Include statix config for linting
