Memory Leak Detection

This handles the detective work of tracking down memory leaks in Node.js and Python apps. You get heap snapshot utilities, profiling helpers, and middleware to monitor memory growth over time. The reference guides cover the usual suspects: event listeners that never detach, forgotten timers, cache bloat, and circular references. It pushes WeakMap and WeakRef pretty hard for caching, which is the right call if you're holding references to objects you don't fully control. Most useful when you're debugging OOM crashes or watching container memory creep up in production. The monitoring patterns are more practical than the basic profiler examples.
