Initial commit: Nomarchy NixOS configuration

An opinionated NixOS configuration with Hyprland, featuring:

- Modular flake-based architecture
- Parameterized user configuration (username, timezone, locale, etc.)
- Classical/antiquity theme with Thomas Cole wallpapers
- Full Hyprland setup with waybar, rofi, swaync
- Custom utility scripts (screenshots, screen recording, WiFi QR)
- Neovim with LSP support
- Interactive installer for existing NixOS systems
- ISO builder for fresh installations

Flake outputs:
- nixosConfigurations.example - Test configuration
- nixosConfigurations.installer - ISO installer
- packages.iso - Bootable ISO image
- apps.default - Interactive installer
- lib.mkHost - Host builder function
- templates.default - Starter template
