Description

Contributes to rapidsai/build-planning#205

This PR adds support for Python 3.14.

Notes for Reviewers

This is part of ongoing work to add Python 3.14 support across RAPIDS.
It temporarily introduces a build/test matrix including Python 3.14, from rapidsai/shared-workflows#508.

A follow-up PR will revert back to pointing at the main branch of shared-workflows once all
RAPIDS repos have added Python 3.14 support.

This will fail until all dependencies have been updated to Python 3.14

CI here is expected to fail until all of this project's upstream dependencies support Python 3.14.

This can be merged whenever all CI jobs are passing.

We _should_ be able to merge in Python 3.14 support PRs without
admin-merges because of limited APIs support, but the `numba` dependency
here needs to be bumped for Python 3.14 testing in `dask-cuda` and
others.

Testing the upstream ucxx fix here by filtering out the asyncio.iscoroutinefunction warning -- this should pass (:crossed_fingers: ) and then once the builds from rapidsai/ucxx#599 are available I'll remove the filter and rebuild

Deprecated in 3.14 `asyncio.iscoroutinefunction` is getting promoted to an error in the `dask-cuda` test suite and causing `LocalCUDACluster` to fail to start.

`inspect.iscoroutinefunction` has been around since 3.5 and is the recommended switch.

Looks great, just don't forget to remove that warning suppression.
