name: server lifecycle cross-platform

# Verifies server memory management and parallel-session lifecycle changes
# compile and the focused unit tests pass on all three
# desktop platforms. GPU backends are disabled here: the changes themselves are
# backend-agnostic (they query memory through ggml_backend_dev_memory), and the
# existing linux/mac/windows workflows already cover CUDA/Vulkan/Metal builds.
