Handle history previous request.

Handle history next request.

Handle paste payloads that resolve to dropped file paths.

Handle paste text from app-level routing when input is not focused.

When the text area is mounted, the paste is always consumed: file paths are attached as images, and plain text is inserted directly.

Handle key events for completion navigation.

Post mode changed message and update prompt indicator.

The prompt glyph update is deferred via call_after_refresh so that callers which also schedule deferred work (e.g. the completion popup) can coalesce both visual changes into a single refresh.

Focus the input field.

Enable or disable the input widget.

Toggle input focus state (e.g., unfocus while agent is working).

Toggle the input's cursor blink without changing focus.

Exit the current input mode (command/shell) back to normal.

Clear/hide the completion popup.

Message sent when input is submitted.

Message sent when input mode changes.

Posted when the user presses a printable key or backspace in the input.

The app uses this to delay approval widgets while the user is actively typing, preventing accidental key presses (e.g. y, n) from triggering approval decisions.
