Proxy URL Validation with Clear Error Messages

Invalid proxy env vars (https_proxy, HTTPS_PROXY, http_proxy, HTTP_PROXY) are now detected and reported clearly at startup and in /doctor.

  • At startup: logs Invalid proxy URL in https_proxy: "<value>" cannot be parsed as a URL. Proxy settings must be a complete URL including the scheme, e.g. "http://proxy.example.com:8080". Fix or unset https_proxy and restart Claude Code.
  • In /doctor's connection section: shows (invalid — ignored; fix or unset the proxy env var) next to the bad value
  • Previously, bare hostnames or partial URLs were passed directly to the HTTP client and could cause confusing failures
Evidence

Proxy URL validator (search for "Proxy settings must be a complete URL including the scheme")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
