Treat uppercase Q as quit shortcut

[puneetdixit200]

Description

Makes the quit shortcut accept uppercase Q as well as lowercase q when no modifiers are present and the user is not in a search field. This helps terminals that report Caps Lock as an uppercase character while leaving the existing uppercase-only shortcuts unchanged.

Issue

This does not close that issue.

Also not exactly sure why you need that test there tbh... that's like, AI slop testing.

[ClementTsang]

Please remove the slop test.
