What to do when ParticleEmitterOptions.maxParticles is full and a new spawn is requested.
drop-oldest(default) — kill the oldest live particle to make room for the new one. Keeps emitter responsive (e.g. bullets always come out).drop-new— silently drop the new spawn. Protects already-visible particles from churn.
