Have updateFormat return MediaFormat

[squadgazzz]

Summary

• updateFormat now returns MediaFormat | undefined instead of void, allowing callers to directly access the format data without needing to use the withFormat callback pattern

Motivation

Currently, the only way to access format data (bitDepth, sampleRate, etc.) after calling updateFormat is through the withFormat listener/callback pattern. This forces callers to wrap the call in a Promise with withFormat just to get the result - e.g. in Inrixia/luna-plugins#222 where we need to log format info.

With this change, callers can simply do:

const format = await mediaItem.updateFormat(quality.audioQuality);
if (format?.bitDepth && format?.sampleRate) {
      // use format directly
}

Details

• Fully backwards-compatible - existing callers that ignore the return value are unaffected
• Returns format on cache hit, undefined when no playback info is available
