An interrupted first download leaves refs/main plus a snapshot folder
without model.bin. snapshot_download(local_files_only=True) returns that
folder rather than raising LocalEntryNotFoundError, so ctranslate2 fails
with RuntimeError "Unable to open file 'model.bin'" and the online path
never ran, leaving STT permanently broken with a misleading error. Fall
through to the download when the local attempt fails that way. The
loading tests are also gated on faster_whisper being installed, so the
module collects when the voice extra is absent.
Review finding: partial-cache RuntimeError bypassed the online fallback.
