Claude Code 2.1.175

This release introduces the `enforceAvailableModels` managed setting, providing organizations with enhanced control over model access. When enabled, this setting ensures that the `availableModels` allowlist strictly constrains even the Default model, redirecting to an allowed model if a disallowed one is selected by default. A key benefit is the prevention of user or project settings from widening a centrally managed `availableModels` list, ensuring consistent and secure model availability throughout an organization.
