Makefile.agent

# Build the distro agent — a lightweight daemon that runs on each Mac mini.
#
# The agent exposes Metal GPU buffers via RDMA and executes shaders on command
# from the head node. It links against the same RDMA transport and Metal
# interop layers as the full distro library, but excludes the coherence
# protocol, scheduler, and Python bindings.
#
# Usage:
#   make -f Makefile.agent
#   ./distro-agent <port> <num_peers>
