Queue Simplification

Status: COMPLETED

Summary

Simplified Queue from ~524 LOC to ~405 LOC. Removed convenience features only used in tests/docs, kept essentials for async media operations.

Why Queue Exists

All writes are async requests. Queue handles:

Supersession (rapid clicks → only last executes)
AbortController propagation
Task lifecycle tracking (pending/success/error)
Error surfacing for UI

Removed

cancel(), flush(), queued getter
TaskScheduler, QueueConfig, schedule param
delay(), microtask, DOM schedulers (raf(), idle())
onDispatch, onSettled hooks

Final API

interface Queue<Tasks> {
  readonly tasks: TasksRecord<Tasks>;
  readonly destroyed: boolean;
  enqueue<K>(task: QueueTask<K>): Promise<Tasks[K]['output']>;
  abort(name?: keyof Tasks): void;
  reset(name?: keyof Tasks): void;
  destroy(): void;
  subscribe(callback: StateChange<TasksRecord<Tasks>>): () => void;
}
