Adds /eval listing page and /product/<slug> detail pages for Windows
Server 2025/2022/2019/2016 and Windows 11 Enterprise evaluation ISOs,
sourced from Microsoft evalcenter without any session flow.
Backend: new /evallinks endpoint fetches evalcenter page, extracts
fwlinks, follows all redirects in parallel, detects arch + locale.
24h cache per product with startup warming so first hit is instant.
Frontend: EvalPage listing at /eval, EvalDetailPage at /product/<slug>
matching consumer structure with downloads, aria2 template, system
requirements, and also-available section. Smart ProductRouter in
App.tsx dispatches slug vs numeric productId. Dock highlights Products
tab for /product/* and /eval routes. CTA banner on home page and
footer link added. sitemap.xml updated with 6 new URLs.
Closes#13
