New client page: filter by core/platform, fetch GitHub Releases and download assets; non-GitHub entries link to website.

New subscription management: create/edit/delete sources, generate secure links, and view access logs & stats.

Subscription output supports Clash/Sing-box/V2Ray, merges multi-source content, and records IP/UA/call counts on server.

Tool pages improved SEO metadata display, clearer error handling, and on-demand component loading for faster first paint.
