Resolve an npm package to its latest published version and dist-tags. Use this when you only know the package name and need the current version, typically before calling get_breaking_changes.

Structured breaking-change diff between two versions of an npm package, computed from its TypeScript type declarations: removed exports, changed signatures, removed/changed class or interface members, plus new exports. Each entry has before/after signatures and a short migration note. The response includes a confidence score: 0.9 when both versions ship bundled types, 0.8 when DefinitelyTyped @types/* declarations were used. Use this before writing or upgrading code that targets a dependency version you are not certain about — e.g. when the installed version is newer than the API surface you know. The first request for a version pair may take up to a couple of minutes while the diff is computed; results are cached after that.
