Summary

• Expose GET /v1/models/catalog through OpenSecretClient as get_model_catalog(), returning the new ModelCatalogResponse (data with context_window/max_context_tokens/capabilities, aliases with target_model, defaults).
• The TypeScript SDK already fetches this endpoint (fetchModelCatalog); the Rust SDK only allowed it through the inference proxy allow-list, so native consumers had no way to size context usage against the selected model.
• Adds test_get_model_catalog mirroring test_get_models.

Test plan

• cargo test --lib (82 passed)
• Live probe against enclave.trymaple.ai: catalog returns 7 models with context windows, 2 aliases (auto:quick -> deepseek-v4-flash, auto:powerful -> kimi-k2-6), and defaults.
• CI integration test run

Could you rebase? I think this was after some of our SDK work but just need to double check. I’m now running CICD tests against an opensecret server that gets pulled in, so you may add integration tests there for good measure if you haven’t already.

Looks good overall. Before merging:

• Please align Rust capabilities with the server/TypeScript contract: chat, vision, reasoning, and tool_use (not audio/video).
• Remove the duplicated models.data.is_empty() assertion.
• Rebase onto current master and let the fresh SDK + desktop CI pass.
