refactor(web-test): этап A.1 — выделить module-level state в core/state.mjs

Состояние движка (browser, page, sessionPrefix, seanceId, recorder, контексты,
константы, normYo, isConnected/ensureConnected/getPage) переехало в
core/state.mjs. Импортируется как live-binding; присваивания в browser.mjs
конвертированы в setX(...) — ESM imports read-only.

Публичный API не меняется (56 экспортов). Регресс 19/19 зелёный.
