Http::pool() sends many requests at the same time through WordPress's bundled WpOrg\Requests transport. A consumer that downloads ~22 images one after another (~45 s) can now fetch them in about the time of the slowest request.

$responses = Http::pool(function (Pool $pool) use ($urls) {
    foreach ($urls as $key => $url) {
        $pool->as($key)->timeout(15)->get($url);
    }
}, ['concurrency' => 10]);

• New Pool and PooledRequest. A pooled request has the full fluent Request API. Its verb methods record the request instead of sending it. Responses come back in the order the requests were added, keyed by as($key) or by the next integer index.
• Request::send_request() is split into build_request() and dispatch(), so pooled and single requests are built by the same code. Single requests still go through wp_remote_request() unchanged.
• The pool does for each request what WP_Http::request() (WP 6.9.4) does: default-argument filters, http_request_args, the pre_http_request short-circuit, wp_http_validate_url/block_request checks, Requests options (SSL/CA bundle, https_ssl_verify, proxy, redirect hooks, cookies, streaming, max_bytes), the response array shape, http_api_debug and http_response.
• Requests that need the network are sent in batches of concurrency (default 10). Short-circuited and rejected requests do not take a slot. A failed request becomes a Response that wraps a WP_Error and never affects the others. A duplicate key or an invalid concurrency throws before anything is sent.
• Fix: Response::failed() now returns true for a WP_Error. It used to return false, because the status read as 0.
• Test stubs: add_filter/apply_filters now run callbacks, and there are stand-ins for the WP HTTP classes and a RecordingPool seam. Adds 36 tests; the full suite passes (935).
• docs/http-client.md, a new CHANGELOG.md, and version 3.3.0.

Verified on the Docker playground (WP 7.0): five requests that each take 1 s took 5.04 s one after another and 1.01-2.02 s pooled. The scoped output keeps WpOrg\Requests and WP_* global.
