EVM address activity profile API

Reads an EVM address's public facts via keyless public RPC (nonce, native balance, code presence) and derives a profile: wallet-vs-contract, an activity tier from the outbound tx count, and funded/dormant signals. Answers 'How active is this wallet?', 'Is this address a contract or a wallet?', 'How many transactions has this address sent?'.
