背景：A6 任务中心需要统一任务协议（九态状态机 / 队列映射 / SSE 事件）与任务落库模型，供 API、worker 与前端共用，避免各端自建枚举。
改动：
- 新增 packages/shared/src/tasks/task-protocol.ts：任务类型、架构 §3.6 九态与允许迁移、5 组 9 队列定义、Outbox/SSE 事件、进度与收敛纯函数；
- 新增 packages/shared/src/schemas/tasks.ts：提交/列表/详情/取消/重试/SSE 的 Zod DTO（body camelCase、query snake_case，列表 { items, next_cursor }）；
- system_configs 新增 task 分组（演练上限 20 项 / 单条成本 0.02 元 / 单条时长 3 秒），seed 按定义幂等；
- Prisma 新增 media_tasks / media_items / task_events 三表与迁移 20261104125003_a6_media_tasks（expand-only，不改旧表）。
影响面：仅新增 shared 导出、配置项与三张新表，旧接口与旧表不受影响。
回滚：撤销提交，并对三张新表执行 prisma migrate resolve/删除（无业务数据）。
验证：shared 197 tests 全绿；typecheck / lint / format:check 全绿；prisma migrate status up to date。
