feat: convert hypr config to Lua and add Chester host

- Add Lua equivalents for hyprland, autostart, keybindings, programs, windowrule
- Add per-host Lua configs (Chester, Rutherford, example) with hostname detection
- Rename old host 'William' to 'Chester'; fix 2x scaling on the 2880x1800 panel
- Update .gitignore to track *.lua host files instead of example-host.conf
