could not start HTTP client

Error message

could not start HTTP client

What it means

Fires in the edit prediction CLI's init when constructing the ReqwestClient (with proxy and User-Agent settings) fails, so the headless evaluation harness has no HTTP client for API calls or language-server downloads.

Solutions

1. Check that the configured proxy URL (settings or HTTP_PROXY env) parses correctly
2. Unset an invalid proxy and retry
3. Verify TLS/runtime initialization succeeded inside the tokio context
