A typed entity/component identity used to capture live component methods.
Signature
ComponentReference[T] pairs a Rust entity ID with a canonical concrete type name. bind[T](entity) validates that the component exists; method calls resolve it again and commit accepted receiver changes transactionally.
This is an interpreter handle, not a Rust borrow or raw memory reference. Access component data with get and set; invoke methods through the reference. Invoking a reference after its entity disappears is an error.
Examples
Capture a live component method
Calling advance updates the stored component, rather than a copied receiver.
