npm, pnpm, Yarn, and registry utilities

Package-manager tools deal with the manifest layer of JavaScript projects: package.json validators that catch typo'd engines fields, dependency-tree analyzers, npm/pnpm/yarn lockfile diffs that surface what actually changed in a PR, monorepo workspace converters, registry URL builders for private mirrors. The bias is toward correctness — these aren't cleanup tools so much as sanity checks before publishing or merging a dep bump. If you've ever shipped a release with a missing peerDependency or a lock that pinned the wrong major, the relevant tool here would have caught it.
