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/

lib/log.sh
