RunMat High-Performance Generational Garbage Collector

A production-quality, thread-safe generational garbage collector designed for high-performance interpreters. Features safe object management with handle-based access instead of raw pointers to avoid undefined behavior.

Global GC functions for easy access

gc_barrier_minor_roots

Get barrier-derived roots for minor GC
