Note

Low Risk
Version and changelog-only release PR with no application logic changes in the diff.

Overview
Release v4.2.2 — bumps the package version from 4.2.1 to 4.2.2 in package.json and package-lock.json, and prepends a 4.2.2 section to CHANGELOG.md (git-cliff).

That release documents fixes merged since 4.2.1: release-plz exits when git-cliff reports no version bump (#566), tar is validated for Zstd support before use (#569), and docs correct the default for cache_key_prefix (#570). This PR does not change action runtime code beyond the version metadata.
