Lua's require() caches modules in package.loaded; without explicit
invalidation, changes to default/hypr/*.lua or ~/.config/hypr/*.lua
won't take effect after hyprctl reload even though hyprland.lua itself
re-runs.
The clear runs unconditionally — benefits both dev-link workflows
(checkout files re-evaluate after every reload) and normal users who
edit their own ~/.config/hypr/*.lua and run omarchy-restart-hyprctl.
Cost is negligible: package.loaded has a handful of entries.
Pattern matches the require_all.lua reload option (which sets
package.loaded[module] = nil before require()), but applied broadly to
the omarchy module namespace at the entry point so individual modules
don't need to opt in.
