Analyzer socket-leak-fgraph

# Name

socket-leak-fgraph - Socket Leakage Flame Graph

This analyzer detects socket resource leaks across all applications by tracking socket creation without corresponding closure. It captures C-level stack traces at socket allocation points and identifies unclosed sockets. The analyzer generates flame graphs showing code paths responsible for socket leaks, helping troubleshoot resource exhaustion issues and improve socket lifecycle management.
