[LM Studio] Multiple agents/models: "Unloading other JIT model X" (JIT auto-evict) then "This model has already been unloaded."

Cause (Documented platform behavior): With auto-evict on, loading a JIT model unloads other JIT-loaded models; handles referring to an unloaded model raise the already-unloaded error. Fix status: documented_behavior Unknowns: - That the already-unloaded error follows specifically from JIT eviction is an inference from the two code paths, not stated in one place. Other error fragments: - by going to LM Studio -> Settings -> Developer -> Turn OFF JIT models auto-evict) - This model has already been unloaded.
