Meta Vens dd896528cc Sensor: the pinger's swept set decides each crossing once; allies credit a published ping return inside the bistatic oval
Deletes the stateless interval crossing (_previousRadius, PreviousRadius, Crossing) and the allied-pinger scan over
other ships' Sensors. The pinging Sensor remembers the subjects its wavefront has reached (_reached), in the beam
or not, and a subject's first sweeping tick inside the radius is its one crossing. On it the pinger paints, credits
itself and posts a PingReturn to each ally; Entity publishes returns with paints (PublishPaints is now
PublishInbox) and the ally's own sensors credit them for one tick at the geometric mean range, inside
Rt x Rr < PingRange^2, through the geometric mean of both legs' obscuration (ruling ally-echo-bistatic-oval).
This commit builds and replaces the sensor the previous commit's tests were written against.
