Proxy no_proxy hostname checks now ignore any username/password embedded in the URL

What

When Claude Code checks a URL's hostname against your no_proxy (or honorNoProxy) settings to decide whether to bypass a proxy, it now clears any username and password from the URL first, before comparing hostnames.

Why

Credentials embedded in a URL (like user:pass@host) could otherwise interfere with matching the hostname against your no-proxy list. Stripping them first makes the comparison rely only on the actual host, so proxy bypass rules behave consistently regardless of whether a URL carries login details.
