1//! Backspace handling across TUI view modes.

3//! Deletes the character before the cursor in whichever
4//! input buffer is currently active — symbol search, bus
5//! filter, model filter, file picker, or chat.
6//!
7//! # Examples
8//!
9//! ```ignore
10//! handle_backspace(&mut app).await;
11//! ```

17/// Delete the character before the cursor.
18///
19/// Delegates to symbol search, bus filter, model filter,
20/// file picker, or chat input depending on the active view.
21/// Resets input mode to `Normal` when the chat input becomes
22/// empty.
