## Summary by CodeRabbit

- **New Features**
- Added a "Recently Updated Documents" feature, allowing users to view a
paginated list of the most recently updated documents within a
workspace.
- Document metadata now includes a "title" field for easier
identification.
- **Tests**
- Introduced new end-to-end tests to verify the recently updated
documents query and its pagination behavior.
