feat: Full test matrix — 10 prompts + quality + performance (#11)

10 practical prompts across 6 categories (factual, code, reasoning,
long-form, summarization, math). Quality evaluation via pattern match.
Performance via tok/s, TTFT, memory. Go/no-go decision at 90% pass rate.

Closes #11.

+TurboQuant Full Test Matrix — Issue #11
+
+Runs 10 practical prompts against both FP16 and TurboQuant KV configs.
+Measures quality (pattern match, perplexity delta) and performance
+(tok/s, TTFT, memory). Generates pass/fail report.
+
+Usage:
+    python3 benchmarks/test_matrix.py --model llama3 --backend ollama
+    python3 benchmarks/test_matrix.py --model qwen3.5 --backend llama-server --kv-type turbo4
+    python3 benchmarks/test_matrix.py --quick  # Run only 3 prompts for smoke test
