ComfyUI wrote straight to the agent's pipe. An agent that restarts and
adopts the replica leaves that pipe with no reader, and ComfyUI's next
progress bar failed with a broken pipe, failing the workflow. It now
writes to a pipe of the gate's, which reads for as long as ComfyUI writes
and passes on what it can.

ComfyUI lists its base directory's custom_nodes before anything else and
exits when there is none.

A model whose profiles run engine comfyui is placed on a node's card like
any other, and makes pictures there. ComfyUI asks for no key, so the agent
starts it behind llmgw comfyui-gate: ComfyUI on the loopback, the gate on
the replica's port demanding the replica's key and letting through only
what the router asks — queueing, waiting, fetching, cancelling. The gate
answers the agent's /health and /v1/models, shows ComfyUI the fetched
weights by their own names, and gives each replica its own base directory.
ComfyUI runs as the gate's child, so its card memory is the replica's.
A node offers the engine when agent.yaml names its ComfyUI
(engines.comfyui.dir). The model's comfyui: block names the workflow and,
for a source that is a set of files, the checkpoint.
