Make the down-flick the soft ball: a short one drops, a long one lobs

Step 3 of the rally rework, Oliver's pick: in rally modes the down-flick
is soft, always, and its length is how far — a dying drop just over the
net at one end, an attacking lob over a net man at the other. One gesture,
one meaning; not the context-armed lob that was cut.

Ballistics from the cut lob (pace derived from the apex); backspin lives
on ball.spin and every bounce planner reads it, netplay sends it. Against
the CPU it was returned ~100% until the real-tennis reasons went in: soft
balls are read late (disguise), a net man reacts to a pass and backpedals
from a lob, and a lobbed or dug-out reply is a weak block. Four new tests;
v363.
