Detailed Description

A static registry tracking the lifetime of C++ objects exposed to JavaScript via Emscripten/WebIDL bindings.

Uses two maps keyed by className, each mapping to a set of pointers:

• alive: objects currently alive
• dead: objects that were alive and are now destroyed

This allows JavaScript wrappers to detect use-after-free by calling isDead(), and enables per-class statistics for debugging.
