[BUG] Quick Launch breaks IME composition behavior on macOS

[LinEvil]

Description

In Quick Launch, pressing Enter while IME composition is active immediately opens the highlighted item (repo/command), instead of committing the IME text.

Expected

• Enter during IME composition should commit the composition text

• Quick Launch updates matching based on the committed text
• A second Enter triggers the action

Actual

• The IME composition is not committed, so the Quick Launch input remains empty and no matching has started
• Despite this, pressing Enter still triggers the action, opening the currently highlighted default repository or command

Environment

• macOS 26.4.1
• Fork 2.66.6
• IME input (e.g. Chinese / Japanese)

Reference
IME works correctly in Create Tag / Create Branch:

• First Enter → commit IME text

• Second Enter → perform action
