feat(crawlers): convert multiple sources from Playwright to Static/RSS

- Added `StaticCrawler` for generic aiohttp+BS4 parsing.
- Added `SkolkovoCrawler` for specialized Next.js parsing of sk.ru.
- Converted ICRA 2025, RSF, CES 2025, and Telegram Addmeto to `static`.
- Converted Horizon Europe to `rss` using its native feed.
- Updated `CrawlerFactory` to support new crawler types.
- Validated changes with unit tests.
