avoid panics gracefully

Replace panic-prone operations like unwrap() and expect() with graceful error handling that provides meaningful feedback. When encountering unexpected conditions, prefer logging warnings and falling back to reasonable defaults rather than crashing the application.

Key practices:

• Replace unwrap() with proper error handling and user-friendly messages
• Use expect() only when the panic condition truly should never occur
• Implement fallback mechanisms when primary operations fail
• Log warnings for unexpected but recoverable errors
• Handle edge cases like binary files or missing data gracefully

Example transformation:

// Avoid this - can panic on unexpected input
let path = output.canonicalize().unwrap().to_string_lossy().to_string();

// Prefer this - graceful error handling
let path = match output.canonicalize() {
    Ok(path) => path.to_string_lossy().to_string(),
    Err(err) => {
        eprintln!("Failed to canonicalize path: {}", err);
        return Err(err);
    }
};

This approach prevents application crashes from unexpected conditions while still providing useful diagnostic information for debugging and user feedback.
