For the boid Fight rule (and when determining friend/enemy health), we need to check if other `ParticleTarget` psys is actually boids as well (their health data is accessed -- which is only present on boid particle systems), otherwise NULL data access crashes. I know, EOL, but simple crash fixers should still get a chance to get in I think. Could also go into LTSes. Pull Request: https://projects.blender.org/blender/blender/pulls/126494
