Function ensureAudioContextRunning

ensureAudioContextRunning(
ctx: ResumableAudioContext | null | undefined,
): Promise<boolean>
Resume an audio context if it is suspended, returning whether it is running afterwards.
Parameters
- ctx: ResumableAudioContext | null | undefined
  The audio context to resume (null/undefined tolerated)
Returns Promise<boolean>
true when the context is running after the attempt
Remarks
Mobile browsers create audio contexts in the suspended state until a user gesture, and resume() outside a gesture may reject or resolve without effect. Call this inside gesture handlers before scheduling audio, and check the result: false means anything scheduled now will be silent.
Example
```
button.onclick = async () => {
  if (await ensureAudioContextRunning(ctx)) {
    playChime(ctx);
  }
};
```
