Closes: BS-3221
Closes: BS-3222

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

- **New Features**
  - Introduced extensions that conditionally register edgeless auto-connect and toolbar widgets with associated effects based on the view context.
  - Added new exports for edgeless auto-connect and toolbar widget views, making them available for external use.

- **Chores**
  - Updated dependencies and project references to include the extension loader for improved module integration.
  - Refined workspace configuration to reflect new package dependencies.

- **Refactor**
  - Streamlined registration and effect logic by removing legacy integration points for edgeless auto-connect and toolbar widgets.
  - Reorganized widget export paths to a more modular directory structure.

- **Bug Fixes**
  - Disabled pointer events on the edgeless navigator black background to prevent interaction interference.
