In the previous iteration, conflict detection was based on top level modules. This would work if all namespace packages correctly omitted the `__init__.py`, but e.g. the nvidia packages include an empty `nvida/__init__.py`. Instead, we track overlapping top level modules during installation and perform conflict analysis after installation, recursing only as far as necessary. See https://github.com/astral-sh/uv/pull/13437 for a list of reported conflicts.
