copilot-swe-agent[bot] 36be8be951 Fix massive scroll on focus return by resetting X11 scroll valuators on focus loss ...

When kitty loses focus and the user scrolls in another
application, X11 XI scroll valuators accumulate position values. When the
user returns to kitty and scrolls, delta (value - v->value) uses the stale
pre-focus-loss value, causing a massive unexpected scroll jump.

Fix: reset scroll valuators (mark them uninitialized) on FocusOut so the
first scroll event after focus is regained sets the baseline without firing
a scroll event.
