Description

Summary

The new --active flag (https://github.com/astral-sh/uv/pull/11189) is a great addition and I think it goes some way to allow uv and conda to work better together. But it does not respect conda environment and only use VIRTUAL_ENV variable.

Would it be possible to add a support for conda environment for --active flag? Simply using CONDA_PREFIX instead of VIRTUAL_ENV when CONDA_DEFAULT_ENV is not base and not empty would be enough, I guess.

Research direction
Investigate the implementation of the active flag in PR #11189 to understand how VIRTUAL ENV is currently used. Then modify the code to also check the CONDA PREFIX environment variable when CONDA DEFAULT ENV is not 'base' and not empty. Ensure that the change respects conda's environment detection behavior. Test with both conda and virtualenv environments.
