SSH服务器启用：修复模块路径和编译错误

修复内容：
- lib.rs: ssh_server模块改为pub导出
- main.rs: 使用markbase_core::ssh_server路径
- port参数：直接使用u16而不是Option<u16>

测试结果：
- ✅ SSH服务器编译成功（0错误）
- ✅ SSH服务器启动成功（port 2024）
- ✅ SSH版本交换成功（SSH-2.0-MarkBaseSSH_1.0）
- ⚠️ SSH_MSG_KEXINIT packet序列化问题（padding计算bug）

下一步：
- 修复packet.rs padding计算逻辑
- 重新测试SSH密钥交换
