Failed to build HTTP client

Error message

Failed to build HTTP client

What it means

ImageAnalyzeTool::new_with_route_client builds the shared reqwest HTTP client (120s timeout, crate TLS settings) in the constructor and expects success. A panic means the reqwest/TLS backend could not initialize — typically missing system CA material or a broken rustls/crypto provider — so the vision tool cannot function at all and fails fast at construction rather than per-request.

Solutions

1. Fall back to a client without the custom TLS builder if reqwest_client_builder fails, and surface image analysis errors per-request instead
2. Return Result<Self, Error> from the constructor so callers can degrade the tool gracefully
3. Check TLS/crypto provider setup (rustls feature flags, CA bundle env) when this fires
