Warmup: run a synthesis before accepting Wyoming connections so MIOpen benchmarks and caches all conv layer shapes. Without this, the first HA request triggers hundreds of benchmark runs and times out. fp16: wrap in try/except so a failed autocast retries in fp32 rather than dropping the request silently.
