feat(web): i18n sync, SEO/GEO improvements, IndexNow key for fxtun.dev

- getDomainLocale: recognize fxtun.dev as EN, auto-persist locale
- getBlogUrl: language-dependent blog URL (ru→fxtun.ru, en→fxtun.dev)
- robots.txt: add 16 AI bots organized by vendor
- llms.txt/llms-full.txt: fix broken links, cross-domain URLs
- vite.config: sitemap defaults (weekly, priority 0.7)
- Add separate IndexNow key for fxtun.dev domain
