torch and onnxruntime both fall back to the CPU without raising, so the agent
that ran CPU-bound for weeks after a driver update leased and checked in like
a healthy one.
- The agent sends its startup accel report on every lease and heartbeat.
- The server keeps a bounded copy on the roster row. A running agent with a
runtime off the GPU becomes `degraded`, with a sentence naming the runtime
and the reason.
- The top nav shows it amber.
- The agent page carries a banner, and its pill reads "CPU only".
Also: the bandwidth field gets the page's − / + stepper, and both number
fields drop the browser's spin arrows.
