Token Buy and Sell Simulation (Honeypot Test)

Replays a real buy and sell of the token on chain state and tells you if you can get out again: buy_succeeded, sell_succeeded, buy and sell tax in percent, honeypot reason, estimated round-trip cost in percent and USD for amount_usd, plus the pools used. Use before buying an unknown token or in a trading bot. EVM chains are simulated; Solana returns status not_simulated with authority and pool checks. No liquidity returns status no_liquidity. Cost excludes LP fees and gas.
