feat: добавить поддержку 20 framework exact modes

Добавлены exact modes:
- vue@vite и vue@webpack
- nuxt@vite и nuxt@webpack
- svelte@vite, svelte@webpack и sveltekit@vite
- angular@application и angular@webpack
- astro@vite
- solid@vite, solid@webpack и solid-start@vite
- preact@vite и preact@webpack
- qwik@vite
- lit@vite и lit@webpack
- alpine@vite и alpine@webpack

Для каждого mode реализованы изолированный adapter, нативный
framework-компонент, declarations, manifest, CSS и внешний asset URL.

Добавлены production integration-стенды с генерацией, typecheck,
сборкой и Playwright-проверкой рендера спрайта и Viewer.

Обновлены Viewer, RU/EN-гайды, README, technical reference и AI skills.
Итоговая матрица включает 29 exact modes.

Проверки:
- 48 unit-тестов
- 29 integration E2E-тестов
