The curl probe can hang or significantly delay post-attach when DNS/TLS or the endpoint is slow/unreachable. Add explicit timeouts (e.g., connect + overall) so Codespaces initialization doesn’t block on a network call, and consider handling transient failures (timeout) as a non-fatal fallback to env-default.

Copilot uses AI. Check for mistakes.
