Ensure Emacs-style Ctrl-b/Ctrl-f work when terminals send bare control
chars.
- Map ^B (U+0002) to move left when no CONTROL modifier is reported.
- Map ^F (U+0006) to move right when no CONTROL modifier is reported.
- Preserve existing Ctrl-b/Ctrl-f and Alt-b/Alt-f behavior.
- Add unit test covering the fallback path.
Background: Ghostty (and some tmux/terminal configs) can emit bare
control characters for Ctrl-b/Ctrl-f. Previously these could be treated
as literal input; with this change both styles behave identically.
This pull request resolves#2391. ctrl + h is not assigned to any other
operations at this moment, and this feature request sounds valid to me.
If we don't prefer having this, please feel free to close this.
This PR:
* Added the clippy.toml to configure allowable expect / unwrap usage in
tests
* Removed as many expect/allow lines as possible from tests
* moved a bunch of allows to expects where possible
Note: in integration tests, non `#[test]` helper functions are not
covered by this so we had to leave a few lingering `expect(expect_used`
checks around
This improves handling of pasted content in the textarea. It's no longer
possible to partially delete a placeholder (e.g. by ^W or ^D), nor is it
possible to place the cursor inside a placeholder. Also, we now render
placeholders in a different color to make them more clearly
differentiated.

## Summary
- support Ctrl-b and Ctrl-f to move the cursor left and right in the
chat composer text area
- test Ctrl-b/Ctrl-f cursor movements
## Testing
- `just fmt`
- `just fix` *(fails: `let` expressions in this position are unstable)*
- `cargo test --all-features` *(fails: `let` expressions in this
position are unstable)*

Wait for newlines, then render markdown on a line by line basis. Word wrap it for the current terminal size and then spit it out line by line into the UI. Also adds tests and fixes some UI regressions.
Added:
* C-m for newline (not sure if this is actually treated differently to
Enter, but tui-textarea handles it and it doesn't hurt)
* C-d to delete one char forwards (same as Del)
* A-bksp to delete backwards one word
* A-arrows to navigate by word
This replaces tui-textarea with a custom textarea component.
Key differences:
1. wrapped lines
2. better unicode handling
3. uses the native terminal cursor
This should perhaps be spun out into its own separate crate at some
point, but for now it's convenient to have it in-tree.
