feat: Add comprehensive tests for contentPattern and glob pattern matching

- Implemented final verification tests for contentPattern to validate behavior with empty strings, dangerous patterns, and normal patterns.
- Created glob pattern matching tests to verify regex conversion and matching functionality.
- Developed infinite loop risk tests using Worker threads to isolate potential blocking operations.
- Introduced optimized contentPattern tests to validate improvements in the findMatches function.
- Added verification tests to assess the effectiveness of contentPattern optimizations.
- Conducted safety tests for contentPattern to identify edge cases and potential vulnerabilities.
- Implemented unrestricted loop tests to analyze infinite loop risks without match limits.
- Developed tests for zero-width pattern detection logic to ensure proper handling of dangerous regex patterns.
