Duplicates desktopenvs/hyprland/ as desktopenvs/hyprlua/ and converts all
Hyprland-specific configs (.conf) to Lua (.lua) using the 0.55+ hl.* API:
hyprland.lua, envvars.lua, monitors.lua, input.lua, autostart.lua,
windowrules.lua, binds.lua. Non-Hyprland tool configs (hyprpaper, hyprlock,
hypridle, hyprtoolkit) remain as .conf. Adds hyprlua.sh installer (user-side
.lua files install to ~/.config/hypr/ for require() resolution) and registers
HyprLua as the recommended DE option in tui-install.sh, marking the old
hyprlang-based Hyprland install as legacy.
Also consolidates hyprland (legacy) env vars into hypr-usr/envvars.conf,
removing duplicates from hyprland.conf and monitors.conf.
