Since app.rs has become quite complex, it might be a good idea to adopt ratatui's component pattern.

+        layout_span(layout, (state.prompt_text.as_ref().into(), prompt_style));
+        layout_span(layout, (" › ".into(), Style::new().cyan().dim()));
+        layout_span(layout, (state.input_state.value().into(), Style::new()));
+        layout_span(layout, (CARET.into(), Style::new()));


I want to change the caret shape to indicate that it is in input mode.

Testing Note

This PR adds the picker component itself, but it's not integrated into any operations yet. To test the picker functionality in action, please check out #470 which converts branch operations to use this picker:

gh pr checkout 470
cargo run

Then try branch operations like:

b b - Checkout branch (uses picker)
b x - Delete branch (uses picker)

You'll be able to see the fuzzy filtering, navigation, and selection in action.

I just wanted to leave some answer at least. I'm a bit busy with other things, but I think this (and the search functionality too) are nice additions to Gitu. I'll try find some time to review and test this properly soon
