fix(rust-packages): pin the preflight macOS runner to macos-14 (#38)

## Summary
- Pin the `preflight` macOS runner to `macos-14`. `macos-latest` rolled to an Xcode whose clang runtime path breaks the compiler-rt link (`ld: library 'clang_rt.osx' not found`), flaking every consumer's macOS preflight. `macos-14` matches the `dist-build` aarch64 runner.

## Test plan
- [ ] `self-test` green; `actionlint` + `yamllint` pass
