Enhance test coverage by adding new cases for file listing, reading, and ripgrep functionalities. Implement tests for hidden files, depth handling, and path normalization in list_files tests. Expand read_file tests to cover line skipping and reading from empty files. Improve ripgrep tests with various pattern matching scenarios, including regex handling and file pattern exclusions.
