Extracted the 629-line checkAll closure from imhotep() into a standalone
makeCheckAll() factory in check-all.ts. Handles temporal dead zone by
passing getUi() getter instead of ui value.
public.ts reduced from 3568 lines to 916 lines (-74.3%). Now contains
only: imports/re-exports, normalizeRuntime, the imhotep() factory
function, property-run internals, and entry points.
