Matthew Ma 275a9a89b6 Keep exposed leading bangs literal in the chat composer (#58412) ...

## Why

Deleting `Yes` from `Yes! I agree.` should leave an ordinary message, without entering shell mode or treating the remaining `!` as a shell command on submission.

## What changed

- Activate shell mode when an edit inserts a leading `!`, rather than when deletion exposes one.
- Use the composer's shell-mode state to classify submissions and preserve that state when restoring the same draft.
- Keep input with whitespace before `!` in normal text mode.

## Testing

Add regression coverage for literal-bang submission and queueing, editing and rendering, Vim repeat and undo/redo, and cancelled history search. Update paste and startup-submission tests to distinguish literal bangs from shell commands.
