Add support for Python 3.15 - #504

CPython 3.15.0rc1 is out, and cibuildwheel 4.2.0 is the first release to build cp315 wheels by default (rc1 is ABI-compatible with the final 3.15 release, so these wheels are safe to publish). NumPy 2.5.2 shipped cp315 and cp315t wheels on 2026-08-09, so 3.15 can be tested like any other supported version rather than being treated as experimental. - Bump the cibuildwheel pin from >=3.0,<4 to >=4.2,<5. - Add cp315/cp315t wheel builds, mirroring the existing cp314 coverage: macOS arm64, Windows x86_64, and manylinux x86_64/aarch64. - Add Python 3.15 to the test and Address Sanitizer matrices, and pass allow-prereleases to actions/setup-python so it can resolve an rc. - Floor NumPy at 2.5.2 on 3.15 in test-requirements.txt, so pip can't quietly fall back to building an older NumPy from source there. - Add the 3.15 classifier to pyproject.toml and setup.py. cibuildwheel 4.0 also made delvewheel the default repair step on Windows. Pedalboard links statically, so this pins the Windows repair-wheel-command back to empty to keep wheel contents unchanged.

Ruff 0.16.0 (2026-07-23) enables 413 rules by default, up from 59. This repo doesn't set `lint.select` in pyproject.toml, so CI's unpinned `pip install ruff` silently picked up the wider default set and started reporting 90 pre-existing findings across pedalboard/. None of those findings relate to Python 3.15 support; they're all pre-existing code that the older default rule set never flagged. Pinning restores a reproducible lint and keeps this PR to one subject. Adopting Ruff 0.16 is worth doing separately: 72 of the 90 findings are auto-fixable via `ruff check --fix` (7 more with --unsafe-fixes). The alternative is to pin the rule set instead of the tool, by setting `[tool.ruff.lint] select = ["E4", "E7", "E9", "F"]` to make the old implicit default explicit.

Thanks @cjacoby-sptfy! FYI releasing this as a new version to actually deploy Python 3.15 support requires two more things, in order:
I'll see if I can put up a small PR to automate this a bit more, so we don't need to update three separate files and then click buttons in the GitHub UI. |
