当前 task 所需的短期 lease/capability。
- JetStream 只持久化和投递 assignment，不保存 executor 生命周期状态。Pod labels/annotations
与 OpenSandbox metadata 是后端运行状态的权威来源，Gitea 是 task 终态的权威来源。
- assignment 使用版本化 envelope 保存完整 Gitea protobuf task，并从 workflow `runs-on`
严格选择 pod 或 vm subject；消费者解码后重新派生 backend 与身份，拒绝被篡改的冗余字段。
- JetStream 的 message ID 等于稳定 assignment ID `gitea-task-<task-id>`，仅用于发布去重，
不承担 executor 生命周期记录。
- worker 按稳定 assignment ID reconcile 后端资源，进程内只保留并发控制等可丢弃状态；
不新增数据库，也不依赖内存中的 runner-to-executor 映射。
- 结果处理顺序固定为回报 Gitea、清理后端、ACK assignment；重投时先查询 Gitea 终态，
