Cannot find module `a2ui.core.schema.manager`

After running the command line:

```terminal
pip install a2ui-agent-sdk
```

Today it is a2ui-agent-sd=0.5.0 [Released: 31 de jul. de 2026](https://pypi.org/project/a2ui-agent-sdk/)

The python code below:

agent.py
```python
from a2ui.core.schema.manager import A2uiSchemaManager
```

returns error: "Cannot find module `a2ui.core.schema.manager`"

It is in src/a2ui/schema/manager.py as mentioned pypi page.

Start with the import in agent.py and reproduce the issue using pip install a2ui-agent-sdk at version 0.5.0. Compare the documented module path with the package layout referenced as src/a2ui/schema/manager.py and the PyPI page. Done means the example and released package agree on a working import path, or the mismatch is clearly documented.
