require() only needs the module's side effects; the returned value is
ignored by hyprland.lua. Chester.lua and example.lua now match
Rutherford.lua in ending after their config statements.
hyprland.lua now just uses its defaults when no hosts/<hostname>.lua
matches, instead of requiring hosts/example.lua. example.lua is kept only
as a documented template for contributors.
Hyprland loads hyprland.lua (not hyprland.conf) when present, so the
hyprlang configs are dead weight. Delete the Hyprland .conf files and
their gitignored host .conf counterparts, leaving only hypridle.conf and
hyprlock.conf (used by separate tools that still use hyprlang).
