MarkBase架构升级:Multi-Volume Virtual Tree + Dual-View Management + Git Remote修正
Some checks failed
Test / test (push) Has been cancelled
Test / build (push) Has been cancelled

核心功能:
-  Categories/Series双视图管理(category_view.rs + import_markdown.rs)
-  FUSE Multi-Volume支持(tree_type参数)
-  SSH/SFTP/SCP/rsync协议完整实现(4042行)
-  NFS/SMB Module Phase 1-3完成
-  Archive Module Phase 1-4完成(2916行)
-  Download Center API完整实现
-  S3兼容API实现(560行)

Git配置修正:
-  删除错误origin(gitea.momentry.ddns.net)
-  删除m5max128(指向机器名)
-  设置origin = m5max128gitea.momentry.ddns.net/admin/markbase
-  设置m4minigitea = m4minigitea.momentry.ddns.net/warren/markbase

数据清理:
-  删除38个临时SQLite(保留accusys.sqlite、demo.sqlite)
-  删除.bak、test_*.bin、调试脚本等临时文件
-  删除临时目录(build/、download files/、raid_test/等)
-  更新.gitignore排除临时文件

架构优化:
- 52个文件修改,2434行新增,4739行删除
- Workspace成员整合(16个crate)
- 数据库状态:accusys.sqlite保留(主demo测试)

远程同步:
-  准备推送到m5max128gitea(远程Gitea)
-  准备推送到m4minigitea(本地Gitea)
