Bearing markers for remembered hostile contacts, labelled with their claimed classes, and a sweep flash per ping

Entity.RememberedHostiles and ClaimedClasses derive from the book; music and the new markers share RememberedHostiles. Markers sit on the remembered bearing, never the subject's position; Search warnings are collected per tick into sweep flashes. Unity code is not compiled in this commit's verification (dotnet tests only).
