- Add Provider field to AgentDefaults struct
- Modify CreateProvider to use explicit provider field first, fallback to model name detection
- Allows using models without provider prefix (e.g., llama-3.1-8b-instant instead of groq/llama-3.1-8b-instant)
- Supports all providers: groq, openai, anthropic, openrouter, zhipu, gemini, vllm
- Backward compatible with existing configs
Fixes issue where models without provider prefix could not use configured API keys.
Add Slack as a messaging channel using Socket Mode (WebSocket), bringing

handling, ack reactions (👀/✅), slash commands,
file/attachment support with Groq Whisper audio transcription, and
allowlist filtering by Slack user ID.
