v0.2.2

• Fix: Continuous mode with --output now appends to a single pcap file instead of creating multiple files
  ** First iteration creates the pcap file with header
  ** Subsequent iterations append packets to the same file
  ** Eliminates the previous behavior of creating output.pcap, output_2.pcap, output_3.pcap, etc.
  ** Results in one consolidated pcap file for the entire continuous run
• Fix: Graceful shutdown handling prevents pcap file corruption when using Ctrl+C
  ** Added signal handler to intercept Ctrl+C (SIGINT) in continuous mode
  ** Program now exits cleanly, properly flushing and closing pcap files
  ** Prevents corrupted pcap files that were unreadable by Wireshark/tcpdump
  ** Shutdown flag is checked during loop iterations and sleep intervals for responsive exit
