"""Verifies left/right arrow keys skip +/-5s (clamped to file bounds) and
that loading a file shows a status bar message. Drives the real
QShortcut-bound keys via QTest.keyClick so it's testing the actual key
binding, not calling _seek_relative directly.

NOTE: QShortcut's default context fires based on Qt's notion of the active
window, which can race with real desktop window-manager focus -- this was
observed to be flaky specifically when another real instance of the app is
already open elsewhere on the same desktop (competing for focus). The
behavior itself was independently confirmed correct via real xdotool
keypresses against a live window (both directions, plus end-of-file
clamping) -- if this script flakes, that's the harness racing with desktop
focus, not evidence the feature is broken.
