📝 Walkthrough

Walkthrough

The pull request refactors version highlighting logic in the package versions component. A new optional selectedVersion prop was added to enable external control of the current version display. Multiple helper functions were introduced to determine which version rows and sections should be highlighted as current, replacing hard-coded "latest" tag checks. The highlighting logic now consistently applies across visible rows, hidden rows, expanded version lists, and major version groups. The parent page component was updated to pass the selected version to the component, allowing dynamic current-version indication throughout the versions display.
