Subject: [PATCH] chore: apply cargo fmt across workspace and update docs

- Run cargo fmt on all Rust crates for consistent formatting
- Update CLAUDE.md with WASM plugin commands and dev.ps1 instructions
- Update wiki: add WASM plugin architecture, rewrite dev environment docs
- Minor frontend cleanup (unused imports)

+## 插件扩展架构
+
+### Q: 为什么用 WASM 而不是 Lua / gRPC / dylib？
+
+**A:**
+
+| 方案 | 安全性 | 隔离性 | 性能 | 复杂度 |
+|------|--------|--------|------|--------|
+| **WASM** | 高（沙箱） | 进程内隔离 | 接近原生（JIT） | 中 |
+| Lua 脚本 | 中 | 无隔离 | 快 | 低 |
+| 进程外 gRPC | 高 | 进程级隔离 | 网络开销 | 高 |
+| dylib | 低（直接内存） | 无隔离 | 原生 | 低 |
+
+WASM 在安全性和性能之间取得最佳平衡。Wasmtime v43 的 Component Model 提供了类型安全的 Host-Plugin 接口，Fuel 机制防止恶意/有缺陷的插件消耗过多资源。

-- 后端 Rust 服务快速重启（无需容器化构建）
+开发环境在 **Windows** 宿主机直接运行所有服务：
+- PostgreSQL 16+ 和 Redis 7+ 通过 Windows 原生安装运行
+- 后端 Rust 服务通过 `cargo run` 快速重启
 - 前端 Vite 热更新直接在宿主机

+
+## 手动启动
+
+### 1. 启动基础设施
+
+确保 PostgreSQL 和 Redis 服务已在 Windows 上运行：
+
+```powershell
+# 检查 PostgreSQL 服务状态
+Get-Service -Name "postgresql*"
+
+# 检查 Redis 是否运行（如果作为 Windows 服务安装）
+Get-Service -Name "Redis" -ErrorAction SilentlyContinue
+
+# 或通过命令行启动 Redis
+redis-server
+```
+
+### 2. 启动后端
+
+```powershell
+cargo run -p erp-server
+```
+
+首次运行会自动执行数据库迁移。
+
+### 3. 启动前端

+# wasm-plugin (WASM 插件系统)
+
+## 设计思想
+
+ERP 平台通过 WASM 沙箱实现**安全、隔离、热插拔**的业务扩展。插件在 Wasmtime 运行时中执行，只能通过 WIT 定义的 Host API 与系统交互，无法直接访问数据库、文件系统或网络。
+
+核心决策：
+- **WASM 沙箱** — 插件代码在隔离环境中运行，Host 控制所有资源访问
+- **WIT 接口契约** — 通过 `.wit` 文件定义 Host ↔ 插件的双向接口，bindgen 自动生成类型化绑定
+- **Fuel 资源限制** — 通过燃料机制限制插件 CPU 使用，防止无限循环
+- **声明式 Host API** — 插件通过 `db_insert` / `event_publish` 等函数操作数据，Host 自动注入 tenant_id、校验权限
+
+## 原型验证结果 (V1-V6)
+
+| 验证项 | 状态 | 说明 |
+|--------|------|------|
+| V1: WIT 接口 + bindgen! 编译 | 通过 | `bindgen!({ path, world })` 生成 Host trait + Guest 绑定 |
+| V2: Host 调用插件导出函数 | 通过 | `call_init()` / `call_handle_event()` / `call_on_tenant_created()` |
+| V3: 插件回调 Host API | 通过 | 插件中 `host_api::db_insert()` 等正确回调到 HostState |
+| V4: async 实例化桥接 | 通过 | `instantiate_async` 正常工作（调用方法本身是同步的） |
+| V5: Fuel 资源限制 | 通过 | 低 fuel 时正确 trap，不会无限循环 |
+| V6: 从二进制动态加载 | 通过 | `.component.wasm` 文件加载，测试插件 110KB |

+## WIT 接口定义
+
+文件：`crates/erp-plugin-prototype/wit/plugin.wit`
+
+```
+package erp:plugin;
+
+// Host 暴露给插件的 API（插件 import）
+interface host-api {
+    db-insert: func(entity: string, data: list<u8>) -> result<list<u8>, string>;
+    db-query: func(entity: string, filter: list<u8>, pagination: list<u8>) -> result<list<u8>, string>;
+    db-update: func(entity, id: string, data: list<u8>, version: s64) -> result<list<u8>, string>;
+    db-delete: func(entity: string, id: string) -> result<_, string>;
+    event-publish: func(event-type: string, payload: list<u8>) -> result<_, string>;
+    config-get: func(key: string) -> result<list<u8>, string>;
+    log-write: func(level: string, message: string);
+    current-user: func() -> result<list<u8>, string>;
+    check-permission: func(permission: string) -> result<bool, string>;
+}
+
+// 插件导出的 API（Host 调用）
+interface plugin-api {
+    init: func() -> result<_, string>;
+    on-tenant-created: func(tenant-id: string) -> result<_, string>;
+    handle-event: func(event-type: string, payload: list<u8>) -> result<_, string>;
+}
+
+world plugin-world {
+    import host-api;
+    export plugin-api;
+}
+```
+
+## 关键技术要点
+
+### HasSelf<T> — Linker 注册模式
+
+当 Store 数据类型（`HostState`）直接实现 `Host` trait 时，使用 `HasSelf<T>` 作为 `add_to_linker` 的类型参数：
+
+```rust
+use wasmtime::component::{HasSelf, Linker};
+
+let mut linker = Linker::new(engine);
+PluginWorld::add_to_linker::<_, HasSelf<HostState>>(&mut linker, |state| state)?;
+```
+
+`HasSelf<HostState>` 表示 `Data<'a> = &'a mut HostState`，bindgen 生成的 `Host for &mut T` blanket impl 确保调用链正确。
+
+### WASM Component vs Core Module
+
+`wit_bindgen::generate!` 生成的是 core WASM 模块（`.wasm`），但 `Component::from_binary()` 需要 WASM Component 格式。转换步骤：
+
+```bash
+# 1. 编译为 core wasm
+cargo build -p <plugin-crate> --target wasm32-unknown-unknown --release
+
+# 2. 转换为 component
+wasm-tools component new target/wasm32-unknown-unknown/release/<name>.wasm \
+    -o target/<name>.component.wasm
+```
+
+### Fuel 资源限制
+
+```rust
+let mut store = Store::new(engine, HostState::new());
+store.set_fuel(1_000_000)?;  // 分配 100 万 fuel
+store.limiter(|state| &mut state.limits);  // 内存限制
+```
+
+Fuel 不足时，WASM 执行会 trap（`wasm trap: interrupt`），Host 可以捕获并处理。
+
+### 调用方法 — 同步，非 async
+
+bindgen 生成的调用方法（`call_init`、`call_handle_event`）是同步的：
+
+```rust
+// 正确
+instance.erp_plugin_plugin_api().call_init(&mut store)?;
+
+// 错误（不存在 async 版本的调用方法）
+instance.erp_plugin_plugin_api().call_init(&mut store).await?;
+```
+
+但实例化可以异步：`PluginWorld::instantiate_async(&mut store, &component, &linker).await?`
+

+- **[[erp-server]]** — 未来集成插件运行时的组装点
+
+---
+
+# 插件制作完整流程
+
+以下是从零创建一个新业务模块插件的完整步骤。
+
+## 第一步：准备 WIT 接口
+
+WIT 文件定义 Host 和插件之间的契约。现有接口位于 `crates/erp-plugin-prototype/wit/plugin.wit`。
+
+如果新插件需要扩展 Host API（如新增文件上传、HTTP 代理等），在 `host-api` interface 中添加函数：
+
+```wit
+// 在 host-api 中新增
+file-upload: func(filename: string, data: list<u8>) -> result<string, string>;
+http-proxy: func(url: string, method: string, body: option<list<u8>>) -> result<list<u8>, string>;
+```
+
+如果插件需要新的生命周期钩子，在 `plugin-api` interface 中添加：
+
+```wit
+// 在 plugin-api 中新增
+on-order-approved: func(order-id: string) -> result<_, string>;
+```
+
+修改 WIT 后，需要重新编译 Host crate 和所有插件。
+
+## 第二步：创建插件 crate
+
+在 `crates/` 下创建新的插件 crate：
+
+```bash
+mkdir -p crates/erp-plugin-<业务名>
+```
+
+`Cargo.toml` 模板：
+
+```toml
+[package]
+name = "erp-plugin-<业务名>"
+version = "0.1.0"
+edition = "2024"
+description = "<业务描述> WASM 插件"
+
+[lib]
+crate-type = ["cdylib"]    # 必须是 cdylib 才能编译为 WASM
+
+[dependencies]
+wit-bindgen = "0.55"        # 生成 Guest 端绑定
+serde = { workspace = true }
+serde_json = { workspace = true }
+```
+
+将新 crate 加入 workspace（编辑根 `Cargo.toml`）：
+
+```toml
+members = [
+    # ... 已有成员 ...
+    "crates/erp-plugin-<业务名>",
+]
+```
+
+## 第三步：实现插件逻辑
+
+创建 `src/lib.rs`，实现 `Guest` trait：
+
+```rust
+//! <业务名> WASM 插件
+
+use serde_json::json;
+
+// 生成 Guest 端绑定（路径指向 Host crate 的 WIT 文件）
+wit_bindgen::generate!({
+    path: "../erp-plugin-prototype/wit/plugin.wit",
+    world: "plugin-world",
+});
+
+// 导入 Host API（bindgen 生成）
+use crate::erp::plugin::host_api;
+// 导入 Guest trait（bindgen 生成）
+use crate::exports::erp::plugin::plugin_api::Guest;
+
+// 插件结构体（名称任意，但必须是模块级可见的）
+struct MyPlugin;
+
+impl Guest for MyPlugin {
+    /// 初始化 — 注册默认数据、订阅事件等
+    fn init() -> Result<(), String> {
+        host_api::log_write("info", "<业务名>插件初始化");
+
+        // 示例：创建默认配置
+        let config = json!({"default_category": "通用"}).to_string();
+        host_api::db_insert("<业务>_config", config.as_bytes())
+            .map_err(|e| format!("初始化失败: {}", e))?;
+
+        Ok(())
+    }
+
+    /// 租户创建时 — 初始化租户的默认数据
+    fn on_tenant_created(tenant_id: String) -> Result<(), String> {
+        host_api::log_write("info", &format!("新租户: {}", tenant_id));
+
+        let data = json!({"tenant_id": tenant_id, "name": "默认仓库"}).to_string();
+        host_api::db_insert("warehouse", data.as_bytes())
+            .map_err(|e| format!("创建默认仓库失败: {}", e))?;
+
+        Ok(())
+    }
+
+    /// 处理订阅的事件
+    fn handle_event(event_type: String, payload: Vec<u8>) -> Result<(), String> {
+        host_api::log_write("debug", &format!("收到事件: {}", event_type));
+
+        let data: serde_json::Value = serde_json::from_slice(&payload)
+            .map_err(|e| format!("解析事件失败: {}", e))?;
+
+        match event_type.as_str() {
+            "order.created" => {
+                // 处理订单创建事件
+                let order_id = data["id"].as_str().unwrap_or("");
+                host_api::log_write("info", &format!("新订单: {}", order_id));
+            }
+            "workflow.task.completed" => {
+                // 处理审批完成事件
+                let order_id = data["order_id"].as_str().unwrap_or("unknown");
+                let update = json!({"status": "approved"}).to_string();
+                host_api::db_update("purchase_order", order_id, update.as_bytes(), 1)
+                    .map_err(|e| format!("更新失败: {}", e))?;
+
+                // 发布下游事件
+                let evt = json!({"order_id": order_id}).to_string();
+                host_api::event_publish("<业务>.order.approved", evt.as_bytes())
+                    .map_err(|e| format!("发布事件失败: {}", e))?;
+            }
+            _ => {
+                host_api::log_write("debug", &format!("忽略事件: {}", event_type));
+            }
+        }
+
+        Ok(())
+    }
+}
+
+// 导出插件实例（宏会注册 Guest trait 实现）
+export!(MyPlugin);
+```
+
+### Host API 速查
+
+| 函数 | 签名 | 用途 |
+|------|------|------|
+| `db_insert` | `(entity, data) → result<record, string>` | 插入记录，Host 自动注入 id/tenant_id/timestamp |
+| `db_query` | `(entity, filter, pagination) → result<list, string>` | 查询记录，自动过滤 tenant_id + 排除软删除 |
+| `db_update` | `(entity, id, data, version) → result<record, string>` | 更新记录，检查乐观锁 version |
+| `db_delete` | `(entity, id) → result<_, string>` | 软删除记录 |
+| `event_publish` | `(event_type, payload) → result<_, string>` | 发布领域事件 |
+| `config_get` | `(key) → result<value, string>` | 读取系统配置 |
+| `log_write` | `(level, message) → ()` | 写日志，自动关联 tenant_id + plugin_id |
+| `current_user` | `() → result<user_info, string>` | 获取当前用户信息 |
+| `check_permission` | `(permission) → result<bool, string>` | 检查当前用户权限 |
+
+### 数据传递约定
+
+所有 Host API 的数据参数使用 `list<u8>`（即 `Vec<u8>`），约定用 JSON 序列化：
+
+```rust
+// 构造数据
+let data = json!({"sku": "ITEM-001", "quantity": 100}).to_string();
+
+// 插入
+let result_bytes = host_api::db_insert("inventory_item", data.as_bytes())
+    .map_err(|e| e.to_string())?;
+
+// 解析返回
+let record: serde_json::Value = serde_json::from_slice(&result_bytes)
+    .map_err(|e| e.to_string())?;
+let new_id = record["id"].as_str().unwrap();
+```
+
+## 第四步：编译为 WASM
+
+```bash
+# 编译为 core WASM 模块
+cargo build -p erp-plugin-<业务名> --target wasm32-unknown-unknown --release
+
+# 转换为 WASM Component（必须，Host 只接受 Component 格式）
+wasm-tools component new \
+    target/wasm32-unknown-unknown/release/erp_plugin_<业务名>.wasm \
+    -o target/erp_plugin_<业务名>.component.wasm
+```
+
+检查产物大小（目标 < 2MB）：
+
+```bash
+ls -la target/erp_plugin_<业务名>.component.wasm
+```
+
+## 第五步：编写集成测试
+
+在 `crates/erp-plugin-prototype/tests/` 下创建测试文件，或扩展现有测试：
+
+```rust
+use anyhow::Result;
+use erp_plugin_prototype::{create_engine, load_plugin};
+
+fn wasm_path() -> String {
+    "../../target/erp_plugin_<业务名>.component.wasm".into()
+}
+
+#[tokio::test]
+async fn test_<业务名>_init() -> Result<()> {
+    let wasm_bytes = std::fs::read(wasm_path())?;
+    let engine = create_engine()?;
+    let (mut store, instance) = load_plugin(&engine, &wasm_bytes, 1_000_000).await?;
+
+    // 调用 init
+    instance.erp_plugin_plugin_api().call_init(&mut store)?
+        .map_err(|e| anyhow::anyhow!(e))?;
+
+    // 验证 Host 端效果
+    let state = store.data();
+    assert!(state.db_ops.iter().any(|op| op.entity == "<业务>_config"));
+
+    Ok(())
+}
+
+#[tokio::test]
+async fn test_<业务名>_handle_event() -> Result<()> {
+    let wasm_bytes = std::fs::read(wasm_path())?;
+    let engine = create_engine()?;
+    let (mut store, instance) = load_plugin(&engine, &wasm_bytes, 1_000_000).await?;
+
+    // 先初始化
+    instance.erp_plugin_plugin_api().call_init(&mut store)?
+        .map_err(|e| anyhow::anyhow!(e))?;
+
+    // 模拟事件
+    let payload = json!({"id": "ORD-001"}).to_string();
+    instance.erp_plugin_plugin_api()
+        .call_handle_event(&mut store, "order.created", payload.as_bytes())?
+        .map_err(|e| anyhow::anyhow!(e))?;
+
+    Ok(())
+}
+```
+
+## 第六步：运行测试
+
+```bash
+# 先确保编译了 component
+cargo build -p erp-plugin-<业务名> --target wasm32-unknown-unknown --release
+wasm-tools component new target/wasm32-unknown-unknown/release/erp_plugin_<业务名>.wasm \
+    -o target/erp_plugin_<业务名>.component.wasm
+
+# 运行集成测试
+cargo test -p erp-plugin-prototype
+```
+
+## 流程速查图
+
+```
+1. 修改 WIT（如需新接口）      crates/erp-plugin-prototype/wit/plugin.wit
+       ↓
+2. 创建插件 crate              crates/erp-plugin-<名>/
+   - Cargo.toml (cdylib + wit-bindgen)
+   - src/lib.rs (impl Guest)
+       ↓
+3. 编译 core wasm              cargo build --target wasm32-unknown-unknown --release
+       ↓
+4. 转为 component              wasm-tools component new <in.wasm> -o <out.component.wasm>
+       ↓
+5. 编写测试                    crates/erp-plugin-prototype/tests/
+       ↓
+6. 运行测试                    cargo test -p erp-plugin-prototype
+```
+
+## 常见问题
+
+### Q: "attempted to parse a wasm module with a component parser"
+**A:** 使用了 core WASM 而非 Component。运行 `wasm-tools component new` 转换。
+
+### Q: "cannot infer type of the type parameter D"
+**A:** `add_to_linker` 需要显式指定 `HasSelf<T>`：`add_to_linker::<_, HasSelf<HostState>>(linker, |s| s)`。
+
+### Q: "wasm trap: interrupt"（非 fuel 耗尽）
+**A:** 检查是否启用了 epoch_interruption 但未定期 bump epoch。原型阶段建议只使用 fuel 限制。
+
+### Q: 插件中如何调试？
+**A:** 使用 `host_api::log_write("debug", "message")` 输出日志，Host 端 `store.data().logs` 可查看所有日志。
+
+### Q: 如何限制插件内存？
+**A:** 通过 `StoreLimitsBuilder` 配置：
+```rust
+let limits = StoreLimitsBuilder::new()
+    .memory_size(10 * 1024 * 1024)  // 10MB
+    .build();
+```
+
+## 后续规划
+
+- **Phase 7**: 将原型集成到 erp-server，替换模拟 Host API 为真实数据库操作
+- **动态表**: 支持 `db_insert("dynamic_table", ...)` 自动创建/迁移表
+- **前端集成**: PluginCRUDPage 组件根据 WIT 定义自动生成 CRUD 页面
+- **插件市场**: 插件元数据、版本管理、签名验证
