The main motivation is miniconda being bad at handling free-threading python (#2807), using uv also reduced CI run time by about 1 minute.

Did a dry run of release build, and uv is capable of detecting MACOSX_DEPLOYMENT_TARGET and building wheels for the targeted macOS version:

39M	dist/mlx_metal-0.32.0-py3-none-macosx_26_0_arm64.whl
39M	dist/mlx_metal-0.32.0-py3-none-macosx_14_0_arm64.whl

That's awesome. Sorry for the super late review. Did you by any chance test the resulting wheels ?

I added a step in the release workflow to run tests with the local wheels:
