Subject: [PATCH] fix(web-search): honor HTTP_PROXY environment variable for
 Brave Search API

The web_search tool was not respecting HTTP_PROXY/HTTPS_PROXY environment
variables, causing 'fetch failed' errors when running behind a proxy.

This fix adds ProxyAgent support for the Brave Search API, similar to how
other tools in OpenClaw handle proxy configuration.

Fixes #27405
