refactor(web-test): структура — engine/ wrapper для внутренних модулей

Перенос всей внутрянки движка под scripts/engine/:
  - core/, forms/, nav/, table/, recording/ → engine/<same>/

Публичные entry-точки остаются в scripts/ корне без изменений:
  - browser.mjs, dom.mjs, run.mjs — компат не ломаем.

Симметричный layout, легко читать с первого взгляда:
  scripts/
    browser.mjs, dom.mjs, run.mjs    ← публичные entries
    engine/                          ← внутренности движка
    (dom/, cli/ — место под будущий распил dom.mjs / run.mjs)

Технические правки после переезда:
  - browser.mjs: ./core/... → ./engine/core/... (23 импорта)
  - engine/*/* модули: ../browser.mjs → ../../browser.mjs (11 импортов)
  - engine/*/* модули: ../dom.mjs → ../../dom.mjs (12 импортов)
  - engine/recording/capture.mjs: dynamic import('../browser.mjs')
    → import('../../browser.mjs')
  - engine/core/state.mjs: projectRoot пересчитан (5 → 6 уровней вверх)
  - Git rename detection срабатывает — история файлов сохраняется
