feat: finalize migration to chezmoi and modernize configuration logic

- Modularize Hyprland config into hyprland.d/
- Implement infinitely scalable monitor/workspace logic using templates and loop-based data structures
- Consolidate host-specific configs (hyprlock, hyprpaper, waybar) into single templates
- Resolve waybar symlink conflict and fix template execution errors
- Integrate chezmoi data variables for scale, resolution, and peripherals
