Subject: feat(hyprland): migrate config to Lua, fix API calls, switch to
 hyprpaper - Set configType = "lua" for Hyprland 0.55+ Lua config format -
 Rewrite window rules to use hl.window_rule({...}) table API - Convert
 keybindings to hl.bind() with _args + mkLuaInline - Fix dispatchers:
 hl.dsp.focus (not window.focus), hl.dsp.focus({workspace=}) (not
 workspace.switch) - Replace swaybg with services.hyprpaper module for
 wallpaper - Fix border colors to use base07 (white) / base03 (grey) with
 rgba() format - Reduce default font size from 16 to 12
