/**
 * `agentsmarket call <skill_id>` — invoke a skill.
 *
 * Payment is handled server-side: server checks buyer's USDC balance on-chain
 * before allowing the call. Client signs an EIP-2612 Permit (preferred over
 * EIP-3009 because USDC on Base mainnet requires msg.sender == to for
 * receiveWithAuthorization, blocking operator relay).
 *
 * Flags:
 *   --payment-tx-hash <hex>        Real tx hash from MetaMask/Trust Wallet.
 *   --inputs <json>                 Pass as JSON string, e.g. '{"key":"value"}'
 *   --no-auto-sign                  Skip automatic Permit signing on 402
 *                                   (default: load identity and auto-sign).
 *
 * On 402 with mode 'eip2612_permit_variant_d', CLI auto-loads
 * ~/.agentsmarket/identity, signs one EIP-2612 Permit (owner=buyer, spender=operator,
 * value=total), computes shared_link, retries.
