* feat: add Railway deployment support with agent auto-discovery
- Add railway.toml for build/deploy config with health checks
- Skip config file requirement when RAILWAY_ENVIRONMENT detected
- Auto-discover existing agent by name on container deploys
- Add findAgentByName() API function for agent lookup
- Add setAgentId() method to LettaBot class
- Add comprehensive Railway deployment docs
One-click deploy flow:
1. Set LETTA_API_KEY + channel tokens
2. LettaBot finds existing agent by AGENT_NAME (default: "LettaBot")
3. If not found, creates on first message
4. Subsequent deploys auto-reconnect to same agent

* Add voice message transcription support (all channels)
Adds OpenAI Whisper transcription for voice messages across all channels:
- Telegram: ctx.message.voice
- WhatsApp: audioMessage via downloadMediaMessage
- Signal: audio attachments from local files
- Slack: audio files via url_private_download
- Discord: audio attachments
Voice messages sent to agent as "[Voice message]: <transcript>"
Configuration (config takes priority over env):
- lettabot.yaml: transcription.apiKey, transcription.model
- Env: OPENAI_API_KEY, TRANSCRIPTION_MODEL
Closes#47

forward a placeholder so the user knows the message was received.

* feat: add non-interactive onboarding and SKILL.md
Add agent-friendly setup flow:
- lettabot onboard --non-interactive flag
- Reads all config from environment variables
- SKILL.md documents env-based setup for agents
- Supports all channels (Telegram, Slack, Discord, WhatsApp, Signal)
- No prompts - ideal for coding agents automating setup

* fix: address non-interactive setup issues
- Add SLACK_APP_NAME for customizable app name (defaults to LETTA_AGENT_NAME or LettaBot)
- Clarify WhatsApp requires WHATSAPP_ENABLED and WHATSAPP_SELF_CHAT to be explicit
- Document all 5 channels supported (Telegram, Slack, Discord, WhatsApp, Signal)
- Fix WhatsApp selfChat default to be explicit false
* docs: recommend non-interactive setup as primary method
Update README per review feedback to show env-based setup first.
This is simpler for most users and ideal for automation.
* docs: rewrite setup to be AI-first per feedback
Make recommended setup AI-focused:
- Show prompt to paste into AI coding assistants
- AI handles clone/install/config autonomously
- Manual wizard becomes Option 2 for human users

Documents how to install and enable the homeassistant skill from ClawdHub.
The skill sync workflow already supports this - just needed documentation.
