This commit restructures the audiobook generation and serving layer to rely exclusively on S3-compatible blob storage, removing the dependency on local filesystem paths. - Bundle `ffmpeg` and `ffprobe` binaries via npm to ensure portability across environments. - Update API routes to stream audio directly from blob storage instead of local disk. - Remove legacy migration endpoints and filesystem-based indexing logic. - Add startup scripts to facilitate the transition from local to remote storage. BREAKING CHANGE: Audiobook functionality is now strictly dependent on S3 configuration. The previous filesystem-based storage method has been removed.
