New Features and Enhancements

PyRel DSL objects now show readable structure in repr(), str(), and .pprint(). Before, inspecting concepts, expressions, fragments, aggregates, refs, fields, and models showed generic values like <ClassName object at 0x...>. Now those representations show the object structure directly, which makes debugging and interactive inspection easier.

Fixed primitive-value lists passed to .in_() inside select() queries so they no longer create temporary data tables or mutate model state. Before, filters like Person.name.in_(["Alice", "Bob"]) could register extra model state as a side effect. Now those select() filters compile as literal unions, leave the model unchanged, and still return the expected results.
