feat: Add Enhanced Memory Editor with toolbar functionality

- Introduced `EnhancedMemoryEditor` class for advanced memory editing capabilities.
- Implemented a toolbar with buttons for jumping to addresses, searching patterns, and managing bookmarks.
- Added popups for address jumping and pattern searching, enhancing user interaction.
- Removed unnecessary style variable pop from `AgentChatWidget` for cleaner UI management.
