feat(tree): checkpoint resource lifecycle work

提交当前顶层 mnote Git 工作区，范围集中在 04-tree-domain 的 resource/trash/filetree 生命周期、mnote-web resource_trash 路由、Convex/Next 兼容接口、sidebar/file-tree 客户端适配、smoke 脚本与对应设计/bug 记录。

不包含被 ignore 的 design/05-editor-mainline/reference-code/leptos-tiptap 嵌套仓库改动。新增 smoke 的测试密码改为运行时读取 MNOTE_E2E_PASSWORD，避免提交明文 credential assignment。
