Add Testing as top-level docs section with per-module specs

New /testing/ section with 6 pages: overview (all specs), evaluator,
parser, router, renderer, and runners. Each page runs tests server-side
(Python) and offers a browser "Run tests" button (JS). Modular browser
runner (sxRunModularTests) loads framework + per-spec sources from DOM.
