Bug: NameError: name 'Response' is not defined when starting server

Describe the bug

Running apiup crashes after printing the route list with a NameError when Litestar tries to inspect the handler signature.

Steps to reproduce

pip install apiup
apiup

Error

NameError: name 'Response' is not defined

Full traceback originates in litestar/utils/signature.py → get_type_hints() → annotationlib.py.

Root cause

from __future__ import annotations makes Python lazy-evaluate all annotations as strings. When Litestar calls get_type_hints() at handler registration time, it resolves -> Response against the global scope — but Response was only imported inside the build_mock_app function body, making it invisible at that point.

Fix

• Move from litestar.response import Response as LitestarResponse to module level
• Change handler return type from -> Response to -> Any to avoid Litestar signature introspection

Environment

• Python 3.14.3
• apiup 0.1.0
• litestar latest
• Fedora (Silverblue)
