Smart Mode Freeze Fix

This update addresses a critical stability issue in Smart Mode.

• Fixed: Resolved a bug where switching page languages (e.g., English ↔ Arabic) caused the page to freeze due to an infinite mutation loop.
• Improved: Enhanced the Smart Mode algorithm to correctly identify and ignore already-processed elements during dynamic content updates.
