fix: ensure all tools work when behind a http proxy (#2065)

Replace custom `http.Transport` with cloned `DefaultTransport` to inherit proxy configuration from environment variables (`HTTP_PROXY`, `HTTPS_PROXY`, `NO_PROXY`). Affects `fetch`, `web_fetch`, `web_search`, `sourcegraph`, `download`, and `agentic_fetch` tools. Fixes enterprise environment compatibility where proxy configuration is required for external HTTP requests.
