/* PR_START p--cte 05 */ Add eq=False to node classes.

This sets `eq=False` for node dataclasses as nodes should be unique, and
equivalence methods should be used for checking as the nodes represent
recursive data structures. Without this, comparisons or using nodes as keys
can be slow as the generated equals function will traverse the recursive
structure.
