The regression was introduced by commit b277a016b which added an early
`return` in handle_button_event that prevented kitty's internal text
selection from starting on focus-transfer clicks to unfocused splits.
Changes:
- In handle_button_event: replace the early return with a local
suppress_child_forwarding flag that prevents PRESS from being forwarded
to child processes in mouse-tracking mode, while still allowing
dispatch_mouse_event to run (which starts text selection)
- In mouse_event's active_drag_in_window release path: clear
suppress_left_mouse_release to prevent stale flags after drags

This ensures that Ctrl+H behaves like Backspace and correctly clears
the pre-edit state, preventing uncommitted characters from remaining
on the screen when using IMEs like the Japanese one on macOS.
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.

On 32-bit platforms Py_ssize_t is int (signed 32-bit), while
os_window->num_tabs is unsigned int. Direct comparison triggers
-Werror=sign-compare. Cast the unsigned side to Py_ssize_t to
silence the warning. The value can never overflow Py_ssize_t
since num_tabs is bounded by the number of open tabs.
Position the window below the notch by reducing the frame height by
safeAreaInsets.top. Create a fullscreen child window behind it with a
colored subview covering just the notch strip, matching the terminal
background color and opacity.
Also fix background_opacity not triggering a chrome update on config
reload.
