📝 Walkthrough

Walkthrough

Updated package manifests to require js-yaml 4.3.1 where used directly or through overrides. Added targeted js-yaml 3.15.0 overrides and version-specific brace-expansion overrides. Updated the Copilot protobufjs override. Removed selected direct dependencies, including gulp-decompress. Applied corresponding changes to rebase manifests and added a changelog entry.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to f53ea

The PR updates js-yaml across multiple dependency manifests, but the rebase changelog omits several of those files. Future rebases could fail to preserve the security override, so the manifest list should be corrected or explicitly accepted before merging.

@RomanNikitenko : since there is no js-yaml in upstream, and it's clearly a transitive deps, i modified to use overrides and updated the rebase rule accordingly.
