* refactor(cc_sqlalchemy): add type annotations * refactor(cc_sqlalchemy): make TableEngine inherit SchemaItem directly SchemaItem is SchemaEventTarget + Visitable formalized — TableEngine was already structurally identical but didn't declare the inheritance, causing a # type: ignore[arg-type] suppression wherever a TableEngine instance was passed to Table(). Switching to SchemaItem makes the relationship explicit and removes the suppression in alembic/impl.py. Visitable.__init__ was a no-op (delegates to object.__init__); replaced with super().__init__(). * formatting --------- Co-authored-by: Joe S <[email protected]>
