v0.0.1-alpha.1

First public alpha. A Go Telegram bot that turns a voice message or video circle
into text with Deepgram.

Added

• DM transcription: send a voice or video circle and receive the text.
• Group /v replies with a public transcript of the replied voice or circle.
• Group /vp is an ephemeral command: a private placeholder inside Telegram's
  15-second window, then editEphemeralMessageText. DM fallback if the edit
  fails. Ordinary non-ephemeral group /vp stays quiet.
• Deepgram Live streaming (nova-3, language=multi) with prererecorded
  Listen fallback. Interim text uses Telegram sendMessageDraft where the
  client accepts drafts.
• file_id cache: store Telegram file id plus transcript, never audio bytes.
  The same file is not sent to Deepgram again.
• First-party Telegram HTTP client. No third-party Bot API SDK.
• Shared core identity via core.touch. Domain tables live in
  voicetotext.*.
• User-facing stats count only successful non-empty transcripts. Empty and
  failed runs are logged only.
• /healthz, Docker Compose for local development, and a WS04 production
  compose file that joins core_net.

Operations

• Local Compose seeds a minimal core schema (deploy/core-init.sql).
• Production uses voicetotext_core on shared core-postgres
  (deploy/ws04/compose.yaml). Core registration is
  core/migrations/009_voicetotext.sql.

Known Limitations

• Alpha: live validation is limited. Group drafts are often ignored by Telegram;
  /v still sends a public final message.
• Privacy mode stays on. Groups do not auto-transcribe every voice.
• Deepgram streaming of an already-downloaded file falls back to REST Listen
  when the WebSocket path fails.

Migrations

• 001_init.sql creates transcripts, jobs, user_stats, and
  runtime_state in the voicetotext schema.
