fix(benchmarks): separate quality measurement from efficiency proxy (issue #63)

- Add --quality flag to run_benchmarks.py that delegates to llama-perplexity
- Clarify token/sec is an efficiency metric, not perplexity
- Ollama cannot provide true logprob-based PPL (no logprob API)
- Quality gate now runs llama-perplexity binary directly when requested

Closes #63

 Supports Ollama and llama-server backends with KV cache type configuration.
 Measures: TTFT, tokens/sec, latency, peak memory.
 
+Perplexity (quality) is NOT measured here tokens/sec is a throughput proxy.
+For actual quality (logprob-based PPL), use --quality flag which delegates to
