Description
Allow subclassing of entities.
Affects:
- Box: should baseBox.get(subclassId) return a subclass entity? Probably so.
- Queries: Querying for the base class should return all sub classes.
- Relations: if a relation references a base class, actual objects may also be sub classes.

Research direction
Start by tracing the Box.get path, query handling, and relation resolution mentioned in the issue. Determine how subclass identities and base-class lookups should behave across these entry points, then define tests covering Box access, base-class queries, and relations before implementation. Done means all three cases consistently return or resolve subclass entities.
