cmsis-pack-manager: Add version 0.6.0 - #2149

Conversation
Builds the Rust core that parses CMSIS-Pack index and PDSC metadata for riscv64, the way upstream's own ci-build-wheel.yml does: maturin with cffi bindings, so the wheel carries libcmsis_pack_manager.so and cffi's ABI mode dlopens it at import. Upstream publishes no riscv64 wheel. The missing ABI tag is honest rather than a hand-set platform tag - nothing is imported as an extension module - so one py3-none-manylinux_riscv64 wheel serves every interpreter, and the further cibuildwheel identifiers only re-run the test suite under each one. Nothing in the 133-crate graph is architecture-specific, and the only piece of upstream's before-all that riscv64 needs is rustup: reqwest reaches TLS through rustls rather than openssl, and the manylinux image already ships libffi-devel and libatomic. rustup has a riscv64 host toolchain for the 1.71.1 that the repository's rust-toolchain file pins, which is what upstream's wheel job installs too.

pip resolves a test dependency by version, not by whether a riscv64 wheel exists for the interpreter under test, so the cp314t leg reached for hypothesis 6.168.0's sdist: that release publishes cp310-abi3 riscv64 wheels, which the three GIL-ful legs install happily and a free-threaded interpreter cannot load at all. The source build then died in cargo - the toolchain this port installs is upstream's 1.71.1, and hypothesis ships a version 4 Cargo.lock. PIP_ONLY_BINARY=hypothesis, scoped to the test phase, stops pip at the newest release that actually has a wheel for each interpreter - 6.165.10 from pypi.riseproject.dev covers cp314t - instead of hand-pinning a version that goes stale as the registry builds newer ones. Checked in the manylinux_2_39_riscv64 image on the free-threaded interpreter: hypothesis 6.165.10 installs and all 11 tests pass.

… on each of cp312-cp314t The queue note read the py3 abi tag as a question mark; it is honest. maturin builds the Rust CMSIS-Pack parser as a cdylib and cffi's ABI mode dlopens it, so nothing is imported as an extension module and one wheel serves every interpreter - the same shape as gotchas 81/145, now recorded as 479. Nothing in the 133-crate graph is architecture-specific (rustls, no openssl, no vendored C), and rustup has a riscv64 host toolchain for the 1.71.1 upstream's own wheel job installs. Built once on cp312 in 15 minutes on the riscv64 runner, tested under all four interpreters, publish dry-run clean. The only riscv64-specific adjustment was PIP_ONLY_BINARY=hypothesis for the free-threaded test leg (gotcha 210).
