[zgjja]

when using modern build system like uv, mmengine cannot use editable install, this PR fix it.

besides, yapf, isort tools can also be replaced by uv in the future for better performance and easier management.

@HAOCHENYE i think this one can be reviewed.

P.S. ruff may be the better tool for linting when working with uv. popular packages like transformers are using it.

Setuptools may not be the best choice for editable installations due to issues like this: microsoft/pyright#3846.

I'm planning to replace setuptools with hatch. Refactoring mmengine with a new lint config is reasonable, but it will introduce many conflicts with existing PRs. I'll need some time to handle this...

Maybe I can also help migrate linting to Ruff—I've recently been using Ruff to format my own development workflow. Although I'm still using setuptools for installation.
