Analyzer go-gco-ref

# Name

go-gco-ref - Go-Land GC Object Reference Flame Graph

This analyzer traces object references and retention paths in Go applications to identify what keeps objects alive in memory. It generates flame graphs showing reference chains from GC roots to allocated objects, helping diagnose memory leaks caused by unintended object retention. The analyzer is essential for understanding complex object lifecycle issues and optimizing memory management in Go applications.
