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

Build-from-checkout cibuildwheel workflow mirroring upstream's
github-deploy.yml, narrowed to Linux/riscv64. setup.py disables its
CLMUL SIMD path automatically outside x86_64/aarch64/arm64, so
riscv64 falls back to the portable scalar C implementation with no
patching needed. abi3 (cp311-abi3) covers cp311-cp314; cp314t is
built separately since it can't use the limited API.
