Package detection doesn't work for PEP518 packages (no setup.py) #136
Description
Describe the bug
Thank you for working on pylyzer. It's great to have a faster alternative to pytype, which is unbearably slow in large codebases.
We are exploring switching from pytype to pylyzer , but right now pylyzder doesn't support PEP518-configured python pakcages.
More specifically, running
> pylyzer
inside a package set up with pyprojec.toml and without setup.py doesn't analyze the whole package, only a single __init__.py file. This is important, because PEP518 is the way uv sets up packages by default and uv is becoming very popular.
Reproducible Code
mkdir pylyzer_bug
cd pylyzer_bug
uv init --package --build-backend setuptools
cat > src/pylyzer_bug/main.py << 'EOF'
def add(x: int, y: str) -> float:
return x + y
EOF
source .venv/bin/activate
pylyzer
Environment
OS: Ubuntu 22.04
Expected behavior
Calling pylyzer in package root analyzes all python package inside the package.
Error log

All checks OK: __init__.py
but it should error out like this:
