+- fix(providers): web-cookie connection-test/cookie-validation probe (zai-web and every other registry-entry web-cookie provider) now honors the configured HTTP/SOCKS proxy — the `/models` probe routed through `directHttpsRequest`'s hardcoded native-fetch bypass, silently skipping proxy resolution even though the executor's actual chat traffic already respected it (#7058)

+// Regression test for #7058 — zai-web (and every other entry-bearing web-cookie
+// provider) never honored a configured HTTP/SOCKS proxy during connection-test /
+// cookie validation.
+//
+// Root cause: validateWebCookieProvider() probed `${baseUrl}/models` via
+// directHttpsRequest(), which hardcodes `bypassProxyPatch: true` — forcing
+// safeOutboundFetch to use the pre-patch native fetch and skip proxy-context/
+// env-var resolution entirely. That bypass was introduced in #3226 as a narrow,
+// documented exception for a single NVIDIA NIM workaround
+// (see tests/unit/proxy-bypass-scope-guard-3226.test.ts) but validateWebCookieProvider
+// adopted it as its default transport from inception (#4023), silently extending the
+// bypass to every web-cookie provider with a registry entry (zai-web among them).
+//
+// This test proves the cookie-validation probe reaches a local forward proxy
+// (via a real CONNECT tunnel — the same mechanism undici uses for both HTTP and
+// HTTPS targets) when one is configured via HTTP_PROXY, exactly like the
+// specialty web-cookie validators (chatgpt-web, grok-web, ...) already do via
+// validationRead/validationWrite.
