difflib-fast 0.3.5

# Build + test, then on a version tag (`vX.Y.Z`) attach wheels + sdist to a GitHub Release.
# crates.io is published manually (`cargo publish`). No PyPI — install the Python package from a
# release wheel or via `pip install git+https://github.com/prostomarkeloff/difflib-fast`.
#
# No secrets needed — the GitHub Release uses the built-in GITHUB_TOKEN.
#
# abi3 (pyo3 abi3-py39) → one wheel per platform/arch works on CPython 3.9+, so no per-Python matrix.
