账户更新

导入ethers和**@kaiachain/viem-ext**软件包，在 web3 上添加 kaia 功能

指定 kairos 链配置，以连接到 Kaia Kairos 测试网络。

使用createWalletClient建立钱包客户端，配置Kairos链、HTTP传输和转换为账户的发送者私钥。

使用ethers.SigningKey.computePublicKey从发送者的私人密钥生成公钥。参数true可确保密钥被压缩。

使用 prepareTransactionRequest 创建账户更新交易请求，指定交易类型、发件人账户、收件人地址和新的公钥。

使用钱包客户端的 signTransaction 方法签署准备好的交易。

使用 kaia_sendRawTransaction 方法将签名交易发送到 Kaia 区块链，并记录交易哈希值。
