fix: add min_reputation + model to DiscoverOptions; closes #4

Add min_reputation and model fields to DiscoverOptions (parity with
TypeScript and Rust SDKs). Wire both into discover_async() query params.
Add test_discover_passes_min_reputation_and_model verifying both params
appear in the outgoing request URL.
