Devices

Tools for discovering wearable/health-tracking device providers and checking whether the current user is
connected to one. Read-only: this catalog has no create/disconnect/delete tool for device connections
specifically -- device connections still surface in list_connections alongside every other
connection type, but establishing or removing one is not covered by any tool in this repo today.

Tool	Description
`list_device_providers`	Lists wearable/health-tracking device providers (e.g. Fitbit, Garmin) and whether the user is connected to each.
`get_device_provider_status`	Checks whether the current user is connected to a single device provider.
`get_device_user_status`	Checks whether a device-user identity exists for the current user and a given device provider.
