ultra low latency graph based stream processing framework

• Fast: ~0.3 ns compiled / ~12 ns interpreted of engine overhead per node cycle, from a topologically sorted DAG execution engine that visits each node once per tick.
• Nitro — three execution tiers, one wiring: interpreted, compiled, or a compiled island — all derived from the same definition, so they cannot drift. Compiled runs 4.4×–37× faster.
