Interface WritableSignal<T>

Reactive primitives for managing state in WaveSurfer. Signals notify synchronously; use batch() to coalesce. computed/effect auto-track dependencies when no dependency array is given, and are always disposable.

interface WritableSignal<T> {
    get value(): T;
    set(value: T): void;
    subscribe(callback: (value: T) => void): () => void;
    update(fn: (current: T) => T): void;
}
