Gemini CLI History Search
I rebuilt Ctrl+R reverse search in Google's Gemini CLI as a reusable hook, so shell history and prompt history share one incremental search.

Debounced, cached incremental search
Multiline prompt renderer
A reusable state model

Multiline terminal rendering
Context-aware windowing and expand/collapse around matched text, so the matching part is actually visible.
