feat(local): add model pool unload to release GPU memory#903
Merged
Conversation
When running multiple models sequentially (e.g. multi-model benchmarks), previously loaded models remained in VRAM causing OOM errors. Adds ModelPool::unload_all() and exposes it as spnl::model_pool::unload_all() so callers can free GPU memory between model runs.
