reqwest::Client::new() queries macOS SCDynamicStore for system proxy
settings, which calls CFBundleGetMainBundle() → readdir() on
target/debug/deps/. With 576K stale build artifacts accumulated in
that directory, each readdir() took 1.3s, causing 15s+ delays when
multiple test processes ran concurrently.
- Disable jsonschema default features to remove unnecessary reqwest@0.13
and rustls-platform-verifier dependencies
- Make reqwest::Client lazy in web_search tool (OnceLock) to avoid
constructing it during profile tests
- Mark validate_api_key_rejects_invalid_key as #[ignore] since it hits
the live Anthropic API (3.2s per invocation)
