Unify core and runner events into struct yasl_event

The core input queue and the yasl_run() runner each had their own event
type, and the runner translated one into the other. Both now share
struct yasl_event in <yasl/yasl.h>: yasl_surface_poll_event() returns the
same events the app event callback receives, so the runner forwards them
unchanged.

Pointer input becomes POINTER_DOWN/UP/MOTION/SCROLL/LEAVE with a named
yasl_pointer_button and a motion delta computed in the input queue. TEXT,
PASTE and DROP share one text payload, scale changes fold into
WINDOW_RESIZE, and every event carries a monotonic time_ns.
yasl_surface_set_mouse_mode() is replaced by
yasl_surface_set_pointer_mode(); no backend implements relative mode yet.

The export check now only counts YASL_API declarations, so function
pointer fields returning enum yasl_app_result are not mistaken for
exports.
