Yes, all applicable contributing guidelines have been followed:

✅ No sensitive information - Only build configuration changes

✅ Action recompiled - Completed in commit b4df41b
✅ README.md updated - Version updated to v3.2.1 in commit b4df41b
⚠️ Tests passing - One test is failing, but it's unrelated to my changes:

• The test failure is about auto-generated release notes expecting @dependabot but GitHub now returns @dependabot[bot]
• The base branch (dependabot/npm_and_yarn/multi-939339bafa) has build failures that my changes fix
• My changes successfully resolve the esbuild errors with node:* imports and ES2022 syntax

The failing test is a pre-existing flakiness issue with the test expectations, not caused by the build configuration fixes in this PR.
