refactor: 消除冗余、统一设计，bump 0.9.1

- 提取 EntryRow/SecretFieldRow 到 models.rs
- 提取 current_actor()、print_json() 公共函数
- ExportFormat::from_extension 复用 from_str
- fetch_entries 默认 limit 100k（export/inject/run 不再截断）
- history 独立为 history.rs 模块
- delete 改用 DeleteArgs 结构体
- config_dir 改为 Result，Argon2id 参数提取常量
- Cargo 依赖 ^ 前缀、tokio 精简 features
- 更新 AGENTS.md 项目结构

Made-with: Cursor
