/**
 * Signs a signature request using the provided signer.
 * This method handles different types of signature requests including personal_sign, eth_signTypedData_v4, and authorization.
 *
 * @param {SmartAccountSigner} signer - The signer to use for signing the request
 * @param {SignSignatureRequestParams} params - The signature request parameters
 * @param {string} params.type - The type of signature request ('personal_sign', 'eth_signTypedData_v4', or 'signature_with_authorization')
 * @param {SignSignatureRequestParams["data"]} params.data - The data to sign, format depends on the signature type
 * @returns {Promise<SignSignatureRequestResult>} A Promise that resolves to the signature result
 *
 * @example
 * ```ts
 * // Sign a personal message
 * const result = await client.signSignatureRequest({
 *   type: 'personal_sign',
 *   data: 'Hello, world!'
 * });
 *
 * // Sign typed data (EIP-712)
 * const result = await client.signSignatureRequest({
 *   type: 'eth_signTypedData_v4',
 *   data: {
 *     domain: { ... },
 *     types: { ... },
 *     primaryType: '...',
 *     message: { ... }
 *   }
 * });
