Move 288 types from global AKSRT_* + inc/classes manual requires into
namespace AKSRT\{Domain} under src/AKSRT/, wire composer.json psr-4,
and slim bootstrap to helpers/modules/hooks only. Split multi-class
widget/gateway files, update admin contract audit paths, and document
the layout in ADR/README.
Disable the global 2-col .content-layout grid on single pages (it was
tiling breadcrumb/article/author/related/comments left-right), add the
missing Zibll utility bridge used by the author/meta bar, and replace
nonstandard <name>/<item>/<badge> tags in the single surface.
Unify TOC ownership, real video episode list, slider overlay, single-query related list, Zibll user-card after-box, and new-route subtitle/meta contracts.
