v1.0.12

Added

• Voice note support. WhatsApp and Instagram voice notes arrive as audio
  attachments with an empty body. The plugin only handled image/*, so audio
  fell through to "[The customer attached a file]" and the agent told customers
  "voice notes aren't supported here in the chat, so please type it out" —
  on a channel where voice notes are how many people prefer to communicate.
  Audio attachments are now transcribed through transcribeAudioFile, with a
  prompt tuned for Nigerian English and code-switching into Pidgin, Yoruba,
  Igbo or Hausa, keeping names, banks and amounts verbatim. The transcript is
  handed to the agent flagged as automatic, so it confirms anything critical
  rather than trusting a mishearing. Files over 25MB are announced but not
  transcribed, and a failed transcription tells the agent to ask what was said
  instead of denying voice notes work. (#43)
