Walkthrough

This pull request performs a routine dependency maintenance update by bumping the js-yaml package from version 4.1.0 to 4.1.1. This is a patch-level update that modifies only the package-lock.json file to reflect the new version's resolved URL and integrity hash. The package remains as a development dependency with an MIT license, and no changes to its dependency tree are included.
