Add explicit [tool.setuptools.packages.find] with include config to prevent
setuptools from discovering asset directories (js/, images/) as packages.
Also add missing aiohttp dependency imported in __init__.py.
Declare Python 3.12 support, replace the hidden pip bootstrap with explicit uv sync guidance, and remove prompt() from the Web UI save flow. Add focused contract coverage for the metadata and frontend defaults.
