## Summary by CodeRabbit

* **New Features**
* Introduced a new clipboard module, making clipboard-related
functionality available for external use.
* Added a comprehensive extension system for the comment editor,
supporting rich text features, widgets, and configurable options.

* **Bug Fixes**
* Improved stability by ensuring comment highlighting features and
toolbar event subscriptions handle missing dependencies gracefully,
preventing potential runtime errors.

* **Refactor**
* Simplified comment editor view manager setup for easier configuration
and maintenance.

* **Chores**
* Updated package exports to expose new clipboard modules and
configurations.
* Removed confirm modal and portal-related logic from the comment editor
component.
* Adjusted temporary store creation to omit adding an extra surface
block under the root page.
