SubsystemClassDesc class

Description of a subsystem class implementation.

Enables instantiation, lookup, and configuration overrides for subsystems managed by SubsystemInstanceRegistry.

Identifies one concrete implementation (serviceClassId) behind a SubsystemTypeDesc category. Callers that only know the SubsystemTypeDesc (e.g. a shared package) never need to reference a SubsystemClassDesc directly; it's the consuming app's job to register the right one — see example/example.dart.
