Subject: [PATCH] ci: build wheels for all supported Python versions and
 platforms
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prior to this, `maturin-action` was invoked without an explicit interpreter
list, so it only built one cp version per OS (cp312 on mac/win, cp38 on
linux). Combined with `macos-latest` now being arm64-only, the v0.9.3 and
v0.10.0 releases shipped just three wheels — leaving Intel-Mac and
current-Python Linux users unable to install.

- Add `macos-13` (Intel) alongside `macos-latest` (arm64).
- Pass `-i python3.10 python3.11 python3.12 python3.13` so maturin builds
  wheels for every interpreter installed by `setup-python`.
- Add a `build-sdist` job so platforms not covered by binary wheels can
  still fall back to a source build.

After merging, tag a new release (e.g. v0.10.1) to re-publish with
complete wheel coverage; the `optimization/` repo can then bump its pins
to `>=0.9.3` without breaking developers on Intel Macs / Linux+cp312.
