Add python-stretch 0.3.1 - #2717

Conversation
python-stretch wraps the header-only Signalsmith Stretch C++ library with nanobind and builds a cp312-abi3 wheel via scikit-build-core. Upstream never tags releases, so the workflow pins the 0.3.1 release commit ac1fbfc, whose tree (with the include/stretch submodule at ffa4598) is byte-identical to the PyPI sdist apart from PKG-INFO. One abi3 build per libc on cp312, re-tested on cp313/cp314. musllinux runs a numpy-free smoke test since numpy has no musllinux riscv64 wheel. The wheel also ships the Signalsmith (MIT) and nanobind (BSD-3-Clause) notices for the code compiled into the extension.

Signalsmith's default preset at 44.1 kHz uses a 5292-sample block and a 1323-sample interval (input latency 2646); the first run asserted the latency value as the interval.
The artifacts end in -manylinux_riscv64/-musllinux_riscv64, so the '-*-riscv64' glob matched neither and the publish dry-run found no wheels.
