ABS was glued onto device A alongside the keyboard and never worked right; it is not needed in practice. Remove it entirely: device A is now keyboard-only, and device B is the relative mouse (motion + buttons incl. middle + wheel). Drops the ptr_mode model (one layout remains), VMCTL_EV_ABS/PTR_*, and the absolute axes. The public input-kind enum keeps its numeric values (MOVE_REL=1, BTN=2, KEY=3, SCROLL=4) so the wire stays compatible -- only MOVE_ABS (0) is removed and its slot reserved; an unknown/0 kind is a no-op. Bump 0.3.11.
