fix: cursor not showing on game start

Issue: When game starts, renderBoard() rebuilds DOM which removes cursor class
Solution: Add gameStatus as dependency to useCursorRender
- Now re-applies cursor after board renders
- Only applies cursor when gameStatus === 'started'

This ensures cursor is visible immediately when game starts at position (0,0).
