feat: 将自定义范式从 localStorage 迁移到数据库存储

**数据库层 (src/db/index.js)**:
- 为 paradigms 表添加 4 个新字段：
  * specialized_prompt: 存储专业化提示词
  * expert_guidelines: 存储专家检查指令（JSON）
  * outline_template: 存储大纲模板
  * recommended_tags: 存储推荐标签（JSON）
- 新增数据库迁移函数 migrateDatabase()，自动为现有数据库添加新列
- 更新 getAllParadigms() 解析新字段
- 更新 addParadigm() 保存新字段
- 更新 updateParadigm() 支持新字段的更新

**Store 层 (src/stores/paradigm.js)**:
- 将存储从 localStorage 改为数据库（IndexedDB/SQLite）
- loadCustomParadigms() 现在从数据库加载，并自动迁移 localStorage 旧数据
- 新增 saveCustomParadigm(paradigm) 用于保存单个范式
- addCustomParadigm() 改为异步，调用数据库保存
- deleteCustomParadigm() 改为异步，调用数据库删除
- updateParadigmField() 改为异步，调用数据库更新
- clearAllCustomParadigms() 改为异步，调用数据库清空
- 迁移后自动清理 localStorage 中的旧数据

**优势**:
- 范式数据现在包含在数据导出中
- 统一的数据管理接口
- 更可靠的数据持久化
- 自动迁移现有数据，用户无感知
