[FEATURE] CTRL-C should clear drafted text - not kill background agents

Problem Statement

The Claude CLI teaches users to use CTRL-C to clear their text and to exit the application. What is less obvious is that it also kills sub-agents and background processes.

That's probably fine, but it's the most destructive behaviour of the three.

Proposed Solution

If the user has un-sent text in their composer and they press CTRL-C, the text should be cleared first.

The TUI should only kill background agents via CTRL-C if the composer is already completely empty.

It could probably also do the "press CTRL-C again to ACTUALLY kill the background process", mirroring the "close claude" use-case for the shortcut.
