Increase message counts across all 14 benchmark test files to reduce run-to-run variance (e.g. PubSub 16B: 10K→50K, FanOut: 10K→15K, SinglePub: 100K→500K, JS tests: 5K→25K). Rewrite benchmarks_comparison.md with fresh numbers from two-batch runs. Key changes: multi 4x4 reached parity (1.01x), fan-out improved to 0.84x, TLS pub/sub shows 4.70x .NET advantage, previous small-count anomalies corrected.
