Build a configuration-matched Cargo archive from Meson and flatten its object members into static libzstd. This gives C consumers one archive even though the migrated Rust objects and remaining C code refer to each other. Shared libraries whole-archive the Cargo output to retain Rust-only ABI exports. The implementation supports Meson 0.50's generated-archive linking rules, matching HUF mode and 32-bit configuration, and documents cross-build target and archiver selection. Test Plan: - fresh Meson both-build smoke consumers and invalidDictionaries - modern static/shared/both, forced-HUF, i686, install, and fuzzer paths - real Meson 0.50 static and shared smoke builds - cargo clippy, cargo clippy --benches, cargo clippy --tests, and nightly fmt Refs: build/meson/README.md archive and cross-build documentation
