/**
 * Resolve the lazy {@link MediaBase.objectURL} promise into a string
 * suitable for direct use in `<audio src>` / `<img src>` /
 * `<video src>` / `<a href download>`. Returns `undefined` until the
 * URL is available.
 *
 * Lifecycle:
 *  - On mount (or when `media` changes) the hook awaits
 *    `media.objectURL`, then commits the resolved string to state.
 *  - On unmount (or when `media` changes) the hook calls
 *    `media.revoke()` to free the object URL slot. The next consumer
 *    that accesses `media.objectURL` mints a fresh URL from the same
 *    `Blob`, so live re-renders just work.
 *  - If the underlying handle errored before settling, the promise
 *    rejects and `useMediaURL` stays at `undefined`. Inspect
 *    `media.error` to surface the failure.
 *
 * Pair with {@link useAudio} / {@link useImages} / {@link useVideo} /
 * {@link useFiles} to bridge SDK media handles into React DOM nodes
 * without manual `URL.createObjectURL` bookkeeping.
