c42ba4f9ab Add BPF dynptr TC demo implementation 
- Implement BPF program for TC ingress using dynptrs to safely parse packet headers and manage variable-length ringbuf records.
- Create user-space loader for the BPF program, allowing configuration of blocked ports and snapshot lengths for TCP payloads.
- Define necessary data structures and constants in header file for both BPF and user-space contexts.
- Add a comprehensive test script to validate functionality, including basic packet capture and port blocking tests.

6d3ba3ea34 feat: Add cgroup eBPF policy guard with TCP, device, and sysctl controls 
- Implemented cgroup-based access control using eBPF with three main functionalities:
  1. Block TCP connections to specified ports.
  2. Deny access to specified devices.
  3. Control sysctl read/write operations.
- Added necessary Makefile and documentation for building and running the policy guard.
