Shadow auto-approve: would require human review. Publishing workflows move to Blacksmith runners, add sccache/rust-cache, and split wasm build from publish — operational and trust changes needing human review.

Summary
Moves compute-heavy Python wheel and npm native-addon matrices to Blacksmith runners while retaining GitHub’s Intel macOS runner, enables maturin sccache, and runs package smoke tests on smaller Blacksmith runners. It also adds Rust caching for crate and WebAssembly releases, shares the WebAssembly cache with regular CI, and separates the Blacksmith-hosted WebAssembly build from the GitHub-hosted publish job so publishing credentials remain isolated.
Summary by cubic
Speed up release publishing by moving heavy build matrices to Blacksmith runners, enabling Rust build caching, and splitting WebAssembly build/publish to isolate credentials. Previously Python wheels and Node native-addons built on GitHub-hosted runners; now they build on Blacksmith, while Intel macOS builds remain on GitHub.
