Subject: [PATCH] lru-dict: add build-lru-dict.yml for riscv64 wheels

lru-dict 1.4.1 is a single pure-C CPython extension (src/lru/_lru.c) with no
third-party build dependencies, so the workflow is a plain build-from-checkout
cibuildwheel run mirroring upstream's own build-and-deploy.yml, with upstream's
own [tool.cibuildwheel] test-extras/test-sources/test-command driving the test
phase unchanged.

1.4.1 was released to PyPI without a corresponding git tag (upstream tagged
v1.4.0 and v1.5.0 around it but never v1.4.1), so the workflow pins the commit
that bumped pyproject.toml's version to 1.4.1, verified byte-identical to the
released PyPI sdist.
