Add hover effects and dynamic anchor computation to Station component

- Integrated `onTextHover` callback for handling text hover states.
- Implemented dynamic anchor calculation using `useMemo` for improved positioning.
- Updated visual feedback by highlighting labels on hover.
- Adjusted offset calculations and added interactive pointer movement refinements.
- Added `packageManager` field to `package.json`.
