Not super feature complete, but I imagine that a reasonable starting point template for anyone interested in creating Slack apps/bots in Rust:

Features and notes:

* Allows the user to interact with a large language model, in this case HF inference API, but should not be hard to adapt to other LLM APIs or local LLMs (I'm planning on doing that with Candle and Mistral).

* Also allows to receive a simple plot from the bot, should be easy to adapt to send more complex plots or other files.

* Authenticating the Slack event payloads was kind of tricky, in particular, as it's handled using HMAC validation of the body and a timestamp header.
