Initial commit: Omeron modular Hyprland setup framework
- Modular installer with gum-based TUI - Fresh-install detection with auto GPU driver selection - Preflight module for system detection (Intel/AMD/NVIDIA) - Core modules: packages, dotfiles, services, SDDM - Optional software installer (Obsidian, Neovim, VS Code, etc.) - Homelab config module with dynamic AGS integration - Two complete themes: Forest Neon and Rose Night - 19 Hyprland control scripts + 4 AGS widgets - Idempotent dotfile deployment with automatic backup - YAML-based configuration, extensible module system - Full logging to ~/.local/share/omeron/
