v0.24.275

Running corral remote pair now turns remote access on automatically before generating the pairing code. Pairing preserves an active service and supports read-only access. Dry runs remain read-only; failed startup does not generate an unusable code.

执行 corral remote pair 时，现在会先自动开启远程连接，再生成配对码。服务已运行时保持现有连接，支持只读配对。演练模式不更改配置；启动失败时不生成无法使用的配对码。
