## Summary by CodeRabbit

- **New Features**
	- Introduced new view extensions for document title, frame panel, and outline fragments, enhancing modularity and extensibility.
- **Refactor**
	- Updated export structure for fragments to support directory-based modules and added dedicated view module exports.
	- Replaced a centralized view extension with individual fragment-based view extensions for improved clarity.
- **Chores**
	- Updated dependencies and TypeScript project references to ensure compatibility and maintainability.
