Merge branch 'develop'

- 更新 components.json，修改 CSS 文件路径为 src/styles/shell.css。
- 移除 tailwind.config.js 中的冗余配置，改为导入 tailwind.shell.config.js。
- 新增 tailwind.pages.config.js 和 tailwind.shared.js，集中管理主题和样式配置。
- 更新多个组件以使用新的样式类和配置，提升代码一致性和可维护性。

+type WorkerRequestMessage = { type: 'start'; payload: WorkerStartPayload } | { type: 'cancel' };
+
+type WorkerResponseMessage =
+  | { type: 'progress'; generationId: number; payload: GenerateProgress }
+  | { type: 'complete'; generationId: number; payload: GenerateResult }

+  generationId: number; // 任务 ID，用于忽略过期响应
+  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`
