/**
 * PauliKeySDK — create and manage scoped agent keys.
 *
 * Pauli Keys are capability-scoped sub-keys derived from a parent `fwag_` key.
 * They follow the child-scope ⊆ parent-scope rule:
 *   - A parent with scopes ["read","pay","swap"] can spawn children with any subset
 *   - A parent with scope ["read"] cannot spawn a child with scope ["pay"]
 *
 * Key format: fwag_<scopes>_<keccak256(parentKey + label + nonce)>
 *
 * @example
 * const workerKey = await agent.keys.create({
 *   label:      "worker-payment-agent",
 *   scopes:     ["pay"],
 *   spendLimit: "100",      // $100 max per transaction
 *   dailyLimit: "500",      // $500 max per day
 * });
 * // workerKey.keyId === "fwag_pay_a3f9c2b1..."
