## Summary by CodeRabbit

- **New Features**
- Middle-clicking on links and references now opens them in a new
browser tab.
- Linux platform detection has been added for improved
environment-specific behavior.

- **Bug Fixes**
- Middle-click paste prevention is now limited to Linux environments
when the relevant setting is disabled and excludes clicks on links and
references.

- **Tests**
- Added end-to-end tests to verify that middle-clicking links opens them
in a new tab for external links, internal links, and reference
documents.
