hopper-benchmark

Measure a voice agent's LLM time to first token on Hopper with its own system prompt and tools over a simulated 10-turn call, and report first-turn and later-turn latency and the prompt-cache hit rate. Changes no code. Use when the user asks "how fast would my agent be on Hopper", "benchmark TTFT", "is prompt caching working" or wants before/after numbers. Not for STT/TTS latency or load tests; to switch the agent to Hopper, use hopper-integrate.
