Memory Leak Audit

This is a checklist-driven audit for catching disposable and event listener leaks in VS Code extension code. You'd reach for it when reviewing code that registers DOM handlers, fixing reported leaks where listener counts grow unbounded, or working with lifecycle callbacks. It walks through six patterns in order: using addDisposableListener for DOM events, Event.once for one-time fires, MutableDisposable for methods called repeatedly, model-tied DisposableStores, resource pool disposal scoping, and test validation. Each rule is validated against actual VS Code PRs where these patterns prevented or fixed real leaks. The practical bit is the sequential checklist format, since missing even one pattern can leak thousands of objects over time.
