WIP splatter feedback round + HANDOFF.md for session continuation

Done (unverified): faster serve cadence in splatter (overT 0.25, serve from
where you stand, flick = instant aimed quick serve), aim-anywhere targeting
relative to the player. Not done: zombie speed ramp (G.splatT exists but is
never incremented), eaten-on-touch death + restart screen. Full state and
plans in HANDOFF.md.
