refactor: improve error handling in directory and file analysis

- Replaced direct comparison of error types with errors.Is for better error handling in both directory.go and file.go.
- This change enhances the clarity and robustness of cancellation handling during analysis processes, ensuring that user-initiated cancellations are managed more effectively.
