Token safety / honeypot check API

Screen an ERC-20 token before buying it: checks if it's a real token, whether the owner can rug it (ownership renounced?), whether it's an upgradeable proxy, how much liquidity exists to sell into, and scans bytecode for dangerous functions. Returns a 0–100 risk score, machine-readable flags, and a plain-English verdict — all from free public RPC reads. Structural check (not yet a buy/sell simulation).
