   This PR restores backward-compatible SQL compilation for true division (/) when force_div_is_floordiv=True by delegating visit_truediv_binary() to SQLAlchemy’s base implementation, which preserves the expected CAST(... AS NUMERIC) behavior. Additional tests were needed because this was a compiler-level regression in generated SQL, so runtime result checks alone would not catch it.

The coverage was added to the existing compiler tests in tests/test_compiler.py (test_division_operator_with_force_div_is_floordiv_default_true and test_division_operator_with_denominator_expr_force_div_is_floordiv_default_true), which already verify nearby / and // behavior for both force_div_is_floordiv=True and False. This is not a new breaking change; it restores the intended behavior of the existing compatibility path while leaving force_div_is_floordiv=False unchanged.
