Adds an `audit` subcommand that fetches quotes from Fynd and external aggregators (KyberSwap, Nordstern, 0x) for a configurable set of token pairs, then re-executes each quote on-chain via eth_simulateV1 to measure the real amount received. - audit.rs: simulation harness using eth_simulateV1 with state overrides for token balance and allowance; falls back to eth_call when the node does not support eth_simulateV1 - erc20.rs: storage-slot detection for standard Solidity mapping layouts (positions 0–20) and OpenZeppelin v5 namespaced storage - aggregator.rs: quote clients for KyberSwap, Nordstern, and 0x; Nordstern non-JSON pseudo-schema responses are mapped to NoRoute - pair_selector.rs: random pair selection from live Tycho pools - Native ETH output is measured by injecting a 10-byte balance-reader contract into simulation state; zeroing sender balance and setting gasPrice=0 ensures the result equals ETH received exactly Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
