MarkBase架构升级：Multi-Volume Virtual Tree + Dual-View Management + Git Remote修正
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）
