Subject: [PATCH] Upgrade to Axum 0.7 and Hyper 1.0 (Breaking change: disabled
 ngrok tunneling). (#1959)

- Axum upgraded to hyper 1.0 and most of the ecosystem switched so it's
our time now
- [ngrok-rust](https://github.com/ngrok/ngrok-rust/pull/137/files)
hasn't yet, and hasn't for several months now, so let's disabled the
feature for the time being.

 ## What is Guidance?
 
-Guidance is a feature that allows users to constrain the generation of a large language model with a specified grammar. This feature is particularly useful when you want to generate text that follows a specific structure or uses a specific set of words or produce output in a specific format. A prominent example is JSON grammar, where the model is forced to output valid JSON.
