Proposed change

The WLED main light controls the entire WLED device, while individual segments represent the LED strips connected to it. This PR exposes that relationship by making the main light an IntegrationSpecificGroup whose members are the segment lights.

As a result, the group_entities attribute on the main light lists all connected LED strip entities, and the group stays up to date as segments are added or removed at runtime.

Part of: #124271

Pull request overview

This PR adds integration-specific grouping to the WLED “main” light entity so it exposes its segment lights via the standard group_entities capability attribute and stays in sync when segments change.

Changes:

  • Add an IntegrationSpecificGroup to WLEDMainLight and update its members on coordinator updates.
  • Add a regression test verifying group_entities updates as segments are added/removed at runtime.
  • Update WLED light snapshots to include group_entities in capabilities/attributes.
