What's Changed

Breaking Changes

• Enhance caching in setup-node with automatic package manager detection by @​priya-kinthali in #​1348

This update, introduces automatic caching when a valid packageManager field is present in your package.json. This aims to improve workflow performance and make dependency management more seamless.
To disable this automatic caching, set package-manager-cache: false

steps:
- uses: actions/checkout@v5
- uses: actions/setup-node@v5
  with:
    package-manager-cache: false

Summary

This PR updates the actions/setup-node GitHub Action from v4 to v6 in both CI and publish workflows. This is a routine dependency maintenance update.

Verdict: Approved — Safe to merge. No code changes required.

Research notes

I reviewed the official actions/setup-node repository for breaking changes between v4→v6:

Breaking changes in v6:

1. Automatic caching enabled for npm projects when packageManager or devEngines.packageManager in package.json is set to npm
2. always-auth input removed (deprecated)

Breaking changes in v5:

1. Caching enabled by default with package manager detection
2. Action runtime upgraded from node20 to node24

Impact on this repo: Neither workflow uses the always-auth input (no migration needed). The workflows don't specify cache: explicitly, so behavior depends on whether typescript/package.json declares a packageManager field — if it does and it's npm, caching becomes automatic (a benefit); otherwise, behavior is unchanged. The action's internal runtime upgrade (node20→node24) doesn't affect the node-version: "22" that the workflow explicitly requests.

Suggested next steps

1. Merge this PR as-is — no changes needed.
2. (Optional follow-up) Consider explicitly adding cache: 'npm' to the TypeScript workflow if you want deterministic caching behavior regardless of package.json contents, or add a packageManager field to typescript/package.json to leverage the new automatic caching.

General findings

None. This is a straightforward, low-risk dependency bump with no regressions identified.
