Python 3.14 compatibility and chores

[dsbferris]

Hi, I upgraded PyO3 to 0.29.0 to support Python 3.14. I did some required fixes and chores.

Notably, I had to remove the repo owner check from the test workflow, to be able to run it myself. You might want to drop that commit (b92d734).

Build and test workflows ran successfully, except for the macos-13 build. No clue why that one got stuck.

Cheers

I needed cp314 support downstream, so I built and tested this branch. Sharing the results since CI hasn't run on the PR — everything below is on macOS arm64, CPython 3.14.4, Rust 1.96.0.

The pyo3 bump is necessary, not just housekeeping. Current master (pyo3 0.24.2) cannot build on 3.14 at all, even with a Rust toolchain present:

error: failed to run custom build command for `pyo3-ffi v0.24.2`
error: the configured Python interpreter version (3.14) is newer than
       [pyo3's maximum supported version]

Because there's no cp314 wheel, pip/uv fall back to the sdist, hit the above, and fail — so 3.14 users currently have no working path at all, not even "install a compiler".

This branch builds clean and passes:

$ uv build --wheel --python 3.14
Successfully built spacy_alignments-0.9.3-cp314-cp314-macosx_26_0_arm64.whl

$ python -m pytest --pyargs spacy_alignments -q
10 passed, 1 skipped

And it unblocks the wider stack. With that wheel available, a clean 3.14 environment resolves and imports the whole spaCy transformer chain:

python             : 3.14.4
spacy              : 3.8.16
spacy-transformers : 1.4.0
spacy-alignments   : 0.9.3
thinc              : 8.3.13
torch              : 2.13.0

spacy-transformers.TransformerModel.v3    : registered
spacy-transformers.TransformerListener.v1 : registered

get_alignments(['fou','gere'], ['fougere']) returns [[0], [0]] [[0, 1]] as expected.

Worth noting spacy-alignments is the only remaining cp314 gap in that chain — spacy, spacy-transformers, thinc 8.3.12+, blis, murmurhash, cymem, preshed, srsly and torch all already publish cp314 wheels. So this one package is what's holding 3.14 back for anyone using spacy-transformers.

Happy to help with anything that would move it along.

Closing this PR due to #17 containing all of this and more. Thanks @nkg for your additional investigation.
