fix: remove unsafe as any casts in modelCache.ts by extending GetModelsOptions type

Add Ollama-specific optional fields (ollamaModelDiscoveryTimeout,
ollamaMaxRetries, ollamaRetryDelay, ollamaEnableLogging) to the ollama
entry in dynamicProviderExtras, so the discriminated union type properly
includes these fields and no as any casts are needed.
