Changing the published package's engines.node from supporting Node 22 to ^24.15.0 drops Node 22 support, which is a breaking change for consumers running on 22.x. If this is intentional, it should be released as a breaking change (e.g., via a Changesets entry and a major version bump); otherwise consider keeping the prior compatibility range and only pinning CI/dev tooling via .nvmrc.
