Dagger usage locally?

Describe the bug

Speedy on the mypy fix @mscolnick!

I still get local test failures too with hatch, but much better than before.

Looking at the failures, I think it's because hatch is trying to bring its own binaries- but I don't have globally accessible shared libraries (failure cases below):

```text FAILED tests/_cli/test_cli.py::test_cli_sandbox_edit - assert None is not None FAILED tests/_cli/test_cli.py::test_cli_sandbox_run - assert None is not None FAILED tests/_cli/test_cli.py::test_cli_edit_sandbox_prompt - AssertionError: assert None is not None FAILED tests/_cli/test_cli.py::test_cli_run_sandbox_prompt - AssertionError: assert None is not None FAILED tests/_runtime/test_manage_script_metadata.py::test_manage_script_metadata_uv - assert '"marimo",' in '' FAILED tests/_runtime/test_manage_script_metadata.py::test_manage_script_metadata_uv_deletion - assert '"marimo",' in '' FAILED tests/_server/api/endpoints/test_editing.py::test_format_cell - AssertionError: assert 'cell-123' in {} FAILED tests/_server/api/endpoints/test_files.py::test_rename - AssertionError: assert {'detail': 'F...ready exists'} == {'success': True} FAILED tests/_server/api/endpoints/test_files.py::test_rename_propagates - AssertionError: assert {'detail': 'F...ready exists'} == {'success': True} ```

Nix is weird- so this is fine- but it would be nice to have a standard env. Dagger almost seems to work in nix. It'd be nice to have something reproducible on all systems

Environment

nix run github:dagger/nix#dagger call backend test

Error:

Code to reproduce

No response

Dagger can be run locally. dagger call backend test works for me.

EDIT: Actually I got the same issue eventually

[kpenfound]

I'm not familiar enough with hatch to know what ERROR tests/_ast/test_codegen.py - OSError: could not get source code might be caused by. Does the execution environment need some other packages like git or something possibly?

[dmadisetti]

marimo needs access to the sources files in the library / tests folder. Seems like path info is getting stripped or is maybe inaccessible. Is the whole source directory mounted?

The hatch command works without dagger, so thinking this is might be a volume exposure problem, or bad python paths
