## Summary by CodeRabbit

- **New Features**

  - Added new toolbar and quick search options for inserting embedded linked and synced documents.

- **Improvements**
  - Updated dependencies and internal references to support the new embed doc functionality across related blocks and components.
  - Enhanced support for edgeless environments with new clipboard and configuration options for embedded docs.
