Summary
Closes #12590
SharedHttpClientbuilds a fast webpki-only client (~0ms) before the full native-certs client (~200ms on macOS). When a remote cache request fires before the native client is ready, the fast client handles it — but it has no custom CA certificates, so connections to self-hosted caches with custom CAs fail intermittently.SSL_CERT_FILEandSSL_CERT_DIRenv vars via file I/O (no Keychain access), preserving the performance benefit while ensuring custom CAs work from the first request.
