feat(input): drop absolute-pointer (ABS) support

Browse Source 
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.
