Require an exact transport match for named discovery policies.

providerMatchesRegistryTransport returns true for zhipu-bigmodel-responses because it is a key provider without preserveCustomDestination. A same-named provider with another baseUrl can therefore receive its models[].slug discovery policy. resolveProviderModelDiscoveryUrl then resolves path: "models" against the effective custom URL, so the custom endpoint can receive the wrong discovery contract. Require an exact adapter and normalized baseUrl match before selecting namedEntry.modelDiscovery, or explicitly exclude this entry from the early-return path. Add a regression test for the mismatched zhipu-bigmodel-responses destination.

Update the stale live-contract comment.

The comment on Lines 2563-2565 says that all three models use 1_048_576 context tokens and low/high/max reasoning levels. The changed metadata records that glm-5-turbo uses 204_800 context tokens and no selectable reasoning levels. Keep the evidence comment consistent with the registry values.

Preserve live model metadata during catalog mapping.

extractProviderModelItems preserves context_window and supported_reasoning_levels, but catalogHintsFromModelsApiItem only reads context_length and reasoning_efforts. Non-seeded discovered models therefore lose their context limit and reasoning ladder before applyProviderConfigHints builds the catalog. Map and validate these fields into contextWindow and reasoningEfforts, then add a regression test in tests/providers/provider-model-discovery-contract.test.ts.
