feat: каркас v2 — Astro 5 + миграция 50 постов из WP + RSS для IPB Importer

- Astro 5 (6.3.6) minimal scaffold с Content Collections для posts/pages
- Тёмная палитра в духе старой темы darkness-10 (тонкая типографика Inter+Lora)
- Layout с шапкой/футером, главной-лентой, страницами категорий и одиночными постами
- RSS (общий + per-category) под IPB RSS Importer: RFC-822 pubDate,
  <guid isPermaLink="true">, <content:encoded> с CDATA, <lastBuildDate>
- RSS_CUTOFF фильтр: архив 2009-2015 на сайте остаётся, в RSS — только новые
- 50 постов и 6 страниц мигрированы из WP (anotherreflctions_ru @ db.hhivp.com)
  через scripts/migrate-wp.mjs (HTML→md без внешних зависимостей)
- sitemap.xml автоматически через @astrojs/sitemap
