Suggestion: Shall we migrate pyenv to uv?

[jinxiao]

We found that pyenv is quite slow, and will build the whole python from scratch which cost a lot of time and not disk efficient.

However we found uv, a new tiny tool which provides a significant performance enhancement and no need to build the python from source code. Some famous project like Pydantic, Airflow are switching to uv as default.

The homepage of uv is: https://github.com/astral-sh/uv

Yes please - just having uv pre-installed would be handy.

I currently use uv to get Python on NodeJS v22 Lambda CodeBuild images, pretty neat and takes like <4seconds to install Python and make a venv. Using uv in other ways as well, but thought this was a really neat use case since the Lambda CodeBuild images are single language, but so much faster.

In the long run this makes sense, but uv isn't stable in all cases yet. For example, astral-sh/uv#1419 and astral-sh/uv#6794.
