fix(http): drop deprecated curl_close calls; resolve Proxy destination lazily

PHP 8.5 deprecates curl_close() (no-op since 8.0) and Libs\Proxy fataled
on class load because SOURCE_URL was evaluated in a static property
initializer. Stamps http with per-component core data for load-verified
clients (aria2, proxy, compreFace).
