Consume nested scope tables in optimized-out asserts by youknowone · Pull Request #7438 · RustPython/RustPython

When -O flag removes assert statements, any nested scopes
(generators, comprehensions, lambdas) inside the assert
expression still have symbol tables in the sub_tables list.
Without consuming them, the next_sub_table index gets
misaligned, causing later scopes to use wrong symbol tables.

Walk the skipped assert expression with an AST visitor to
find and consume nested scope symbol tables, keeping the
index aligned with AST traversal order.
