コントラクト

• A class applying EquatableMixin compares equal and produces identical hash codes to matching instances across deep nested collections, evaluating lists order-sensitively and sets order-insensitively.
• EquatableMixin allows classes in single-inheritance hierarchies to obtain value equality and hash code parity based on overridden props.
• Nested lists in props require matching element order, whereas nested sets compare equal regardless of element insertion order.
• Deeply nested collections including maps of lists evaluate equality recursively down to leaf elements.
• Equal EquatableMixin instances properly deduplicate in Set collections and look up correctly as Map keys.
• Props containing null values or empty props lists are safely compared without runtime exceptions.
