🌟 [Good First Issue] Improve Error Messages in Scanner Module

[superninja-app]

🎯 Objective

Enhance user experience by making error messages more descriptive and actionable.

📝 Description

Current error messages in the scanner module are generic and don't provide clear guidance to users. We need to improve them to be more specific and helpful.

🔧 Tasks

1. Review all error messages in core/src/scanner.rs
2. Make messages more descriptive with specific context
3. Add suggested actions for users to resolve issues
4. Update tests to cover new error messages

📁 Files to Modify

• core/src/scanner.rs
• core/tests/scanner_tests.rs

🎨 Example

// Current
return Err("Scan failed".to_string());

// Improved
return Err(format!("Scan failed: Unable to access file '{}'. Check file permissions and ensure the file is not in use.", file_path.display()));

✅ Acceptance Criteria

• All error messages are descriptive and actionable
• Users can understand what went wrong and how to fix it
• All existing tests pass
• New tests added for error scenarios
