Description

Generic ECS system that resets dirty state for configured component types.

Template Parameters

TMemberHandle	Member/registry handle type used to access ECS components.
TComponentSpecs	Component type specifications resolved via TComponentSpec::type<TMemberHandle>.

For each configured component type, the system iterates all entities with Active<TMemberHandle> enabled and calls clearDirty() on the component instance.
