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)
