OKX Build X / Skill Arena

Preflight before you trade.
Sign the exact plan the guard executes.

PreflightX verifies a live X Layer swap, checks balance, allowance, concentration, token age, slippage, price deviation, gas, and market-data freshness, then signs the exact `executeWithPreflight` struct. In guard mode it signs a guard-compatible Uniswap execution route instead of raw OKX aggregator calldata.
