DebugBus type

The shape of root.debug. Subscribe to receive every DebugEvent until the returned unsubscribe is called.

The bus replays a snapshot of the *live controller tree* to every new subscriber synchronously inside subscribe(...) — so a panel that mounts after createRoot() sees the existing tree immediately, not just future events. Event types other than controller:* are not buffered.

queryEntries() returns a fresh inspector snapshot — current state of every cached entry. Useful for "what's in the cache right now?" views.

Signature:

type DebugBus = {
  subscribe(handler: (event: DebugEvent) => void): () => void;
  queryEntries(): DebugCacheEntry[];
};
