release(secrets-mcp): 0.5.9 — users.key_version 与会话失效；Web 条目解密 API 与列表增强

通过读取 entry_id/secret_name/secret_value 调用 secrets_update 让服务端用当前密钥重加密。附带模板 CSV，.gitignore 忽略 *.pyc。

+## 版本控制
+
+本仓库使用 **[Jujutsu (jj)](https://jj-vcs.dev/)** 作为版本控制系统（纯 jj 模式，无 `.git` 目录）。
+
+### 常用 jj 命令对照
+
+| 操作 | jj 命令 |
+|------|---------|
+| 查看历史 | `jj log` / `jj log 'all()'` |
+| 查看状态 | `jj status` |
+| 新建提交 | `jj commit` |
+| 创建新变更 | `jj new` |
+| 变基 | `jj rebase` |
+| 合并提交 | `jj squash` |
+| 撤销操作 | `jj undo` |
+| 查看标签 | `jj tag list` |
+| 查看分支 | `jj bookmark list` |
+| 推送远端 | `jj git push` |
+| 拉取远端 | `jj git fetch` |
+
+### 注意事项
+- 本仓库为**纯 jj 模式**，无 `.git` 目录；本地不要使用 `git` 命令
+- CI/CD（Gitea Actions）仍通过 Git 协议拉取代码，Runner 侧自动使用 `git`，无需修改
+- 检查标签是否存在时使用 `jj log --no-graph --revisions "tag(${tag})"` 而非 `git rev-parse`

 3. 提交前运行 `./scripts/release-check.sh`（版本/tag + `fmt` + `clippy --locked` + `test --locked`）。若脚本不存在或不可用，至少运行 `cargo fmt -- --check && cargo clippy --locked -- -D warnings && cargo test --locked`。

+### 类型（Type）
 
-`type` 字段用于软分类，系统会自动将历史遗留类型映射为标准化类型：
+`type` 字段用于软分类，由用户自由填写，不做任何自动转换或归一化。常见示例：`server`、`service`、`account`、`person`、`document`，但任何值均可接受。
-- `git-server`、`database`、`cache`、`queue`、`storage` 等 → `service`（原始值存入 `metadata.subtype`）
-- 新增条目时建议使用标准类型：`server`、`service`、`person`、`document`
-- 类型映射在 `crates/secrets-core/src/taxonomy.rs` 中定义
