v2.3.7: add non-Cloudflare mirror fallback for blocked regions

Browse Source 
Users in Russia/Ukraine where Cloudflare IPs are blocked can now
download game files via htdwnldsan.top (direct VPS → MEGA redirect).
Both manifest fetch and archive downloads try mirrors automatically
on ETIMEDOUT/ECONNREFUSED errors.
