v0.0.1-alpha.2

File uploads now go to Deepgram prererecorded Listen instead of Live streaming.

Changed

• Transcribe sends the downloaded Telegram file to POST /v1/listen. Default
  Content-Type is audio/ogg when Telegram does not provide one.
• Live WebSocket streaming remains in the client but is no longer the file
  upload path.

Fixed

• Empty or mis-detected audio containers are less likely to fail Deepgram
  because files are sent as prererecorded OGG rather than a raw stream.
