feat: enhance Perl tree-sitter queries with comprehensive patterns

- Improved documentation with detailed comments explaining each query pattern
- Added support for modern Perl OO constructs (class, method, role statements)
- Enhanced variable declaration and assignment tracking
- Better organization with clear section headers
- Maintained backward compatibility with original implementation
- Added comprehensive test suite for Perl language support
