# Objective

Fixes #59129.

`vim::HelixJumpToWord` currently treats its two-character target labels
as text input. When an IME is active, the printable label keys can
therefore enter the IME composition window instead of completing the
jump.

## Solution

- Treat an active Helix jump as command input rather than character
input, preventing the platform input handler from preferring the IME for
its label keys.
- After normal keybinding resolution, handle action-less, unmodified
label keydowns directly from the keystroke's ASCII-equivalent key. This
preserves label matching on non-ASCII keyboard layouts while leaving
Escape, custom bindings, and Ctrl/Alt/Cmd/Function shortcuts untouched.
- Stop propagation after consuming a label key so the platform does not
subsequently forward it to the IME.
- Keep the existing committed-text handling as a fallback for other
input paths.

This is complementary to #61270: that PR handles pending GPUI keybinding
chords before IME input, while this change handles Helix jump labels
after the initiating action has resolved. The changes are also
file-disjoint.

## Testing

- Added a regression test using the issue's `s` → `vim::HelixJumpToWord`
binding. The test verifies that:
  - no GPUI keybinding chord is pending;
  - Helix jump does not accept text input or prefer the IME;
  - both raw label keydown events are consumed; and
  - the expected jump completes.

- Manually tested on macOS with both ABC and Japanese Romaji input
sources.
