bench: Gemma 4 tool calling benchmark — 100 prompts (#796)

Benchmark script comparing Gemma 4 vs mimo-v2-pro on tool calling.

100 prompts across 6 categories:
- File operations (20): read, write, search
- Terminal commands (20): system info, process management
- Web search (15): documentation, comparisons
- Code execution (15): calculations, parsing
- Parallel tool calls (10): concurrent operations
- Edge cases (20): complex, ambiguous prompts

Metrics:
- Schema parse success rate
- Tool execution success rate
- Argument validity rate
- Average latency
- Token cost

Usage:
  python3 benchmarks/tool_call_benchmark.py --model1 gemma3:27b --model2 xiaomi/mimo-v2-pro
  python3 benchmarks/tool_call_benchmark.py --model1 gemma3:27b --limit 10

+tool_call_benchmark.py — Benchmark Gemma 4 tool calling vs mimo-v2-pro.
+
+Runs 100 diverse tool calling prompts through each model and compares:
+- Schema parse success rate
+- Tool execution success rate
+- Parallel tool call success rate
+- Average latency
+- Token cost per call
+
+Usage:
+    python3 benchmarks/tool_call_benchmark.py --model1 gemma3:27b --model2 xiaomi/mimo-v2-pro
+    python3 benchmarks/tool_call_benchmark.py --model1 gemma3:27b --limit 10  # quick test
+    python3 benchmarks/tool_call_benchmark.py --output benchmarks/results.json
+
+Requires:
+    - Ollama running locally (or --endpoint for remote)
+    - Models pulled: ollama pull gemma3:27b, etc.
