新增: F-260619-01 任务可关联灵感(tasks.idea_id 1对1 单向)

- df-storage V20 迁移:tasks 加 idea_id TEXT REFERENCES ideas(id)(填预留空位,
  幂等 column_exists 探测)+ V9_SQL 同步 + TaskRecord.idea_id + task_repo SQL/SELECT + 白名单
- AI 工具 create_task 加 idea_id 参数;update_task 经白名单自动支持
- IPC commands/task.rs CreateTaskInput 加 idea_id
- 前端 types TaskRecord/CreateTaskInput idea_id + TaskDetail.vue 关联灵感展示
  (router-link 友好 title 非裸 id)+ i18n
- 补 idea_id 字段:df-mcp tools / df-nodes 测试 helper
- 单向 1对1,Option 可空,复用 projects.idea_id 模式,老任务 None 兼容

自验: df-storage 47 passed(含 V20 2)+ workspace EXIT 0 + vue-tsc EXIT 0
