feat: industrial 50-model benchmark with rate limiting and resume

+"""
+Industrial-grade 50-model benchmark for EU AI Act Compliance Auditor.
+
+Handles NIM's 40 RPM rate limit with:
+  - Sequential model execution (one model at a time)
+  - Per-call rate limiting (1.5s minimum between LLM calls)
+  - Exponential backoff on 429s (2s, 4s, 8s, 16s)
+  - Incremental JSON output (saves after each model)
+  - Resume capability (skips models already in output)
+  - Timeout per episode (5 min)
+
+Usage:
+    python benchmark_all.py --space https://Itachi1824-compliance-auditor-env.hf.space
+    python benchmark_all.py --space ... --resume  # skip already-scored models
+    python benchmark_all.py --space ... --model qwen/qwen3.5-122b-a10b  # single model
