fix(download): removed 行再次提交 / 接管时复活，同 hash 第二个订阅计划取消（H1、M3/M6）

Browse Source 
- 提交遇到同 (实例, hash) 的 removed 行：清 removed_at、状态回到 queued / submitting、改挂新计划、generation+1；
- 接管（adopt）冲突时 removed 行同样复活为 adopted 行；
- 完成事件幂等键按 generation 换代，复活后完成仍能触发整理；
- 订阅计划遇到任务行已挂着别的计划：本计划取消（torrent_in_use_by_plan:<计划>）并释放 Slot 预留，不再留下没有任务的 submitted 孤儿；手动计划仍经 import_plan_id 挂到已有任务。
