/**
* Singleton manager for cloud-provider authentication status (AWS Bedrock,
* GCP Vertex). Communicates auth refresh state between auth utilities and
* React components / SDK output. The SDK 'auth_status' message shape is
* provider-agnostic, so a single manager serves all providers.
*
* Legacy name: originally AWS-only; now used by all cloud auth refresh flows.
