"""Verifies the four interaction changes requested after the first review:
- clap detection moved to a Tools menu (no more buttons in the layout)
- clicking anywhere on the slider track jumps straight there
- dragging the slider seeks live (via sliderMoved), not just on release
- dropping a file onto the player widget loads it

Drives real Qt events (QMouseEvent, QDropEvent) against the actual
MainWindow/PlayerWidget classes rather than calling internal methods
directly, so this proves the actual event wiring, not just the logic
behind it.
