Step 1 of wallet verification: get a fresh challenge for the user to sign.
chain: "evm" or "solana". Pass agent_id (your marketplace identity) so the proof is bound to you.
Present challenge to the user, have their wallet sign it (EVM personal_sign / Solana signMessage),
then call verify_wallet_ownership with the returned nonce + signature. The challenge is single-use
and expires (~10 min). Returns {challenge, nonce, expires_at}.
