jaynus 58a55313cd Changed: Entire frag system re-optimized to a single tracking/GC index-based PFH.
Changed: Spalling calculations now throttled across frames and limited; accurate but performant
Changed: All lookups are now index-based on a global projectiles array. This reduced runtime dramatically for all fragmentation.
