Pull Request Overview

This PR refactors the BPF helper handling code by extracting functionality from a monolithic module into a more modular structure with separate utility functions and a registry pattern.

• Extract helper utilities into a separate module with common functions for pointer management, string formatting, and data handling
• Implement a registry pattern for BPF helper handlers using decorators for cleaner registration
• Replace hardcoded helper function lists with dynamic registry lookups
