Asger F 5772ee4d9b YEAST: add NodeRef type, YeastDisplay trait, and source text storage ...

Introduce NodeRef as a typed wrapper around node arena IDs. Captures in
desugaring rules are now bound as NodeRef instead of raw usize, which
prevents accidental misuse and enables source-text-aware rendering.

Add the YeastDisplay trait as an alternative to Display: its
yeast_to_string method receives the Ast, allowing NodeRef to resolve to
the captured node's source text instead of printing a numeric ID.

Store the original source bytes in the Ast so that NodeContent::Range
values (from synthesized literal nodes) can be resolved back to text.

Update yeast-macros to emit NodeRef-typed capture bindings and use
Into::<usize>::into where raw IDs are needed. The #{expr} template
syntax now uses YeastDisplay instead of Display.

The effect is visible in the corpus tests: operator nodes now correctly
render as e.g. operator "+" instead of operator "3".
