fix(测试数据生成器): 修复规则覆盖保存误创建重复规则

覆盖同名规则时 handleSave(true) 未传入已有规则 id，save() 走新建分支
导致旧规则保留且产生同名重复项，getByName 仍返回旧数据。

-以下行为以 `src/` 源码为准；设计文档中的旧版 class API、`metadata`/`options` 嵌套结构已废弃。
-
-### Worker 任务 ID（`generationId`）
-
-`useGenerator` 每次调用 `generate()` 递增 `generationIdRef`，经 `start` 消息传入 Worker。Worker 所有响应（`progress` / `complete` / `error`）均携带同一 `generationId`。
-
-- **取消**：`cancel()` 先递增 ID 再发送 `cancel`，使进行中的 Worker 响应被主线程忽略；Worker 每生成 100 行让出事件循环以处理 cancel。
-- **快速重试**：新任务 ID 大于旧响应时，旧消息被丢弃，避免 UI 状态错乱。

+使用 localStorage 存储规则数据:
-
-| 函数 | 说明 |
-| ---- | ---- |
-| `getAll()` / `getById()` / `getByName()` | 读取 |
-| `save()` / `update()` / `deleteRule()` / `duplicate()` | 写入；失败时返回 `null` 或 `false` |

-| `search()` / `getRecent()` | 搜索与最近使用 |
-| `exportRules()` / `importRules()` | 导入导出 JSON 数组 |
-| `clear()` | 清空全部规则 |
-
-写入失败（如 `QuotaExceededError`）时，内部 `setAll()` 返回 `false`，`save`/`update` 返回 `null`，`deleteRule` 返回 `false`，并在控制台输出 `[ruleStorage] 保存规则失败`。调用方须检查返回值，避免误报成功。

-  | { type: 'start'; payload: WorkerStartPayload }
-  | { type: 'cancel' };
-
-type WorkerResponseMessage =

-  fields: FieldConfig[];
-  count: number;
-  csvMode: boolean;
-}
-```
-
-### useGenerator Hook
-
-`src/pages/TestDataGenerator/hooks/useGenerator.ts` 负责 Worker 生命周期与 `generationId` 管理：
-
-- Worker **复用**：同一 Hook 实例内只创建一次，出错后 `terminate` 并在下次重建
-- **开始生成**：`generate(fields, count, csvMode?)` 递增 `generationId` 并 post `start`
-- **取消**：`cancel()` 递增 ID（使旧响应失效）并 post `cancel`；取消完成的 `complete` 不写入 `error` 状态
-- **响应过滤**：`onmessage` 中若 `data.generationId !== generationIdRef.current` 则忽略
-
-```typescript
-const generate = (fields: FieldConfig[], count: number, csvMode = false) => {
-  if (isGenerating) return;
-  const generationId = ++generationIdRef.current;
-  worker.postMessage({ type: 'start', payload: { generationId, fields, count, csvMode } });
-};
-
-const cancel = () => {
-  if (workerRef.current && isGenerating) {
-    ++generationIdRef.current;
-    worker.postMessage({ type: 'cancel' });
-    setIsGenerating(false);
-  }
-};
-```
-
-### Worker 实现要点
-
-`src/workers/generator.worker.ts`：
-
-- 按 `field.generatorId` 查找生成器；选填字段按 `nullRate` 随机置 `null`
-- 唯一性：≤1000 条随机+重试；>1000 条优先 `generateAtIndex`
-- 每 `YIELD_EVERY`（100）行 `await setTimeout(0)`，以便处理 `cancel`
-- 进度：每 1000 条或最后一行 post `progress`

-### ruleStorage 写入失败处理
-
-`ruleStorage.ts` 使用函数式导出（非 class），存储键为 `testDataGenerator_rules`，最多 `MAX_RULES = 20` 条。
-
-写入经内部 `setAll()` 完成；`localStorage.setItem` 抛错（如配额超限）时返回 `false`，并 `console.error`，**不会部分提交**：
-
-| 方法 | 写入失败返回值 | 常见失败原因 |
-| ---- | -------------- | ------------ |
-| `save()` | `null` | 达上限、规则不存在（更新时）、`setItem` 异常 |
-| `update()` | `null` | 规则不存在、`setItem` 异常 |
-| `deleteRule()` | `false` | 规则不存在、`setItem` 异常 |
-| `duplicate()` | 仍可能返回对象但数据未持久化 | 见源码：`duplicate` 未检查 `setAll` 返回值（已知缺口） |
-
-调用方应检查返回值后再展示成功 Toast。页面层参考 `FieldList.tsx`：`save`/`update` 返回非空才提示「规则已保存/已更新」。
-
-规则仅持久化 `name`、`description`、`fields` 及时间戳/使用统计；生成数量与导出格式由页面状态管理，不写入规则。
-
 ### useStorageState 初始化防覆盖
 
 `useStorageState` 在挂载时从 storage 异步加载。写入 storage 需满足以下任一条件：
