"""通用任务管理框架：任务类型注册 + 设备分组 + 任务计划 + 定时调度 + 重试 + 持久化。
|
||
|
||
设计目标：可扩展，未来加非抖音任务只需注册新的 Task 类。
|
||
|
||
核心概念：
|
||
TaskType — 任务类型（如"抖音养号"），可注册，含默认参数和 worker 工厂
|
||
DeviceGroup — 设备分组，持久化到 SQLite（core.models.DeviceGroup）
|
||
TaskJob — 任务计划（类型+目标+参数+调度+重试），持久化到 SQLite（core.models.TaskJob）
|
||
TaskManager — 统管调度器、分组、任务、运行实例、状态
|
||
|
||
定时：APScheduler BackgroundScheduler，cron 触发后为每个目标设备起 worker。
|
||
支持三种调度模式：
|
||
once — 手动/立即执行，不注册 cron
|
||
cron — 仅注册启动 cron（到点启动 worker）
|
||
cron_stop — 注册启动 cron + 停止 cron（到点启动，到点停止）
|
||
重试：单设备 worker 失败后按 retry.max_attempts 重试，间隔 retry.delay。
|
||
并发：同一 serial 同时只允许一个 worker，避免冲突。
