Do you need to update your uv version?

Hmm maybe I am doing something wrong, but running uv lock does not make any further changes.
I have updated uv to 0.9.4, which should be the latest version, and still the same.
Feel free to fix if you know how!

For Python versions before 3.14, the Zstandard support is currently provided by the
zstandardlibrary. The API of this library is different from the one in the standard library (compression.zstd), which results in two different implementations of theZstdDecoderclass.This PR removes the
zstdandarddependency in favor of the backport ofcompression.zstd.Fixes #3693
Full disclosure: I'm the author and maintainer of
backports.zstd, and the maintainer ofpyzstd(which code was used as a base for the integration into Python). I also helped with PEP-784 and its integration into CPython.
