Crate elicit_egui 

elicit_egui — dual-mode MCP tools for egui widget creation.

Provides tools that operate in two modes:

1. Runtime mode — each tool returns a JSON description that can be rendered by an egui runtime or inspected as JSON.
2. Emit mode — each tool’s parameters can generate idiomatic egui Rust code via the elicitation code-emission pipeline.
