v0.9.1 — Whisper service now opt-in

Fixes a startup error that occurred when the Whisper transcription container image was unavailable. The whisper service is now opt-in via a Docker Compose profile and is no longer pulled on a standard docker compose up -d.

Changed

• docker-compose.yml — whisper service moved to profiles: [whisper]; removed depends_on: - whisper from the bot service so the bot starts cleanly without it
• README.md — Quick Start adds the optional --profile whisper command; Recording section documents both transcription backend options; added Read Message History to the required bot permissions list; added git clone step
• .env.example — added comment explaining that WHISPER_MODE=local requires --profile whisper

Upgrading

If you were previously running the bundled Whisper container, start it explicitly going forward:

docker compose --profile whisper up -d
