Each component that uses external_files (audio_file, speaker media_player, ...) currently calls download_content once per file inline inside a per-item config validator. With ~24 cached audio files in a Home Assistant Voice PE config, that means ~24 sequential HEAD round-trips, even when every response is a 304. This adds download_content_many(items, ...) which fans the per-file checks out across a ThreadPoolExecutor (capped at 16 workers so configs with hundreds of files don't open hundreds of sockets), then refactors audio_file and speaker.media_player to collect URLs at the list level and call the batch helper once instead of downloading inside each per-item validator. Wall time for the validation phase drops from sum(latency) to roughly max(latency) when the cache is warm.
