Preflight API

Read-only Base L2 gas conditions computed directly from chain data: current base fee, recent percentiles, realised volatility, congestion state, and an 80% forecast range for a chosen horizon. This is supporting context for timing a transaction, not a trade instruction. Every figure is reproducible from public Base RPC data.
