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.
Wire existing HeroManager/BannerManager into page-display routes and
component loaders, fix banner REST round-trip (show_meta + optional title),
and retarget operator deep-links to the real slide managers.
Move header-slider outside main, render fluid zones once, default the
latest stream to plain posts by date, and cut dual-render/perf waste so
published posts and hero/banner structure match the zibll contract.
