ast.parse() without optimize=True doesn't error on invalid AST type

[iritkatriel]

>>> ast.parse(ast.Constant(42))
Constant(value=42, kind=None)


>>> ast.parse(ast.Constant(42), optimize=True)
Traceback (most recent call last):
  File "<python-input-4>", line 1, in <module>
    ast.parse(ast.Constant(42), optimize=True)
    ~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.14/ast.py", line 53, in parse
    return compile(source, filename, mode, flags,
                   _feature_version=feature_version, optimize=optimize)
TypeError: expected Module node, got Constant

(This came up while implementing PEP 765 #130080).
