Pull Request Overview

This PR fixes issue #163 by adding animation support for arrow content/text that appears after the arrow drawing animation completes. The change ensures that when arrows are animated, their content remains hidden during the arrow drawing phase and becomes visible only after the animation finishes.

• Added content animation that synchronizes with arrow drawing animation
• Exported animation duration constant for reuse across components
• Updated slides documentation to demonstrate animated arrow functionality
