[3.0] Enhance data handling and improve code readability

[live627]

This branch is focused on performance optimizations for package lists. Most changes focus on temporary string management and code readability.

• Rewrites tar reader to minimize temporary string creation
• Refactors directory traversal code for improved readability
• Extracts data only when certain a file is needed, reducing unnecessary operations
• Assigns individual sorting variables to each list for better data management
• Removes ID display from output
• Applies HTML entities during display rather than storing them in source
