Pull request overview

This PR updates GitHub Actions dependencies/configuration to address Node.js 20-related deprecation warnings in CI, and applies whitespace/formatting cleanups across workflows and documentation.

Changes:

• Pin/upgrade several GitHub Actions used in CI/release workflows (e.g., checkout/setup-node/setup-python, commitlint action).
• Switch commitlint configuration from CommonJS (.js) to ESM (.mjs) and update the workflow to reference it.
• Remove trailing whitespace / adjust minor formatting in YAML and README.
