Hull no longer depends on FightSystem: plugin, world, region, ground visibility and hidden blocks are passed in. HullRegion is the common block box hulls work on. The generic HullHider<K> manages one hull per key and does the block, entity and REntity tracking; FightHullHider keeps the fight specific parts (team hulls, viewer rules, state dependent registration). Entities are now checked against the hull with block coordinates, so entities in the bottom layer and at the max z edge are handled correctly.
