Move ~94 root class shells and root *-traits into domain directories (core, auth, user, credits, content, payment/gateways, forum, shop, sms, ai, messages, extensions, widgets, settings, admin). Update bootstrap require paths, co-locate traits with owners, fix forum/user relative requires, drop duplicate shop controller requires, and wire home-modules load. Path-only; class names and init order unchanged.
