<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **New Features**
  - Introduced a new pointer graphics module with tools and quick tool integration for edgeless surfaces.
  - Added a quick tool button for pointer interactions in edgeless mode.
  - Exposed new extension points for pointer graphics and effects.

- **Improvements**
  - Integrated pointer graphics as a dependency into related packages.
  - Enhanced toolbar context to support additional surface alignment modes.
  - Added conditional clipboard configuration registrations for edgeless contexts across multiple block types.

- **Removals**
  - Removed legacy tool and effect definitions and related quick tool exports from edgeless components.
  - Streamlined extension arrays and removed unused exports for a cleaner codebase.
  - Deleted obsolete utility functions and component registrations.

- **Chores**
  - Updated workspace and TypeScript project references to include the new pointer graphics module.
