Client: Python 3.14 support

[MonkeyCanCode]

This PR adds support for python 3.14. Beside the max supported version of python, I also had to bump the version of pyroaring (this is from pyiceberg) as the one in uv.lock is pointed to v1.0.3 and pyiceberg has following:

    "pyroaring>=1.0.0,<2.0.0",

The problem here is pyroaring version before v1.0.4 doesn't support Python 3.14:

https://github.com/Ezibenroc/PyRoaringBitMap/blob/1.0.3/setup.py#L107
https://github.com/Ezibenroc/PyRoaringBitMap/blob/1.0.4/setup.py#L107 -> first added here

This was previously not supported earlier as couple dependencies were not 3.14 ready: #3509

+1 Thanks for adding 3.14, @MonkeyCanCode ! Is it OK to deprecate older versions like 3.10?

3.10 is EOL on Oct 31st 2026. So I think we should still support it.
