长期调度接口。长期目标是让 controller 作为兼容 Gitea Runner 协议的调度器直接注册、
声明 labels、领取 task,并把已领取 task 交给 Pod/VM executor;路线与迁移边界见

# Gitea Runner 协议调度器路线
## 目标
长期形态不依赖 `workflow_job` webhook 发现工作。controller 本身作为 Gitea Runner
协议客户端注册,并声明 `self-hosted`、`pod` 和 `vm` labels;它只在后端存在可用容量
时领取 task,然后将该 task 交给一个一次性 Pod 或 microVM 执行。
```text
Gitea RunnerService
│ Register / Declare / FetchTask
▼
dynamic-runner scheduler
│ 已领取的 task + lease
├── Pod executor
└── microVM executor
│ logs / state / result
└──────────────────────► Gitea
```
这与“收到 webhook 后临时注册另一个 act_runner”不同。`FetchTask` 已经完成任务分配,
不能再期待 Gitea 把同一个 task 分配给随后启动的 runner。协议调度器必须让 executor
执行已经领取的 task,并继续完成日志、状态、心跳、取消和最终结果上报。
## 设计约束
- 对 workflow 的接口保持 `[self-hosted, pod]` 和 `[self-hosted, vm]` 不变。
- scheduler 在没有对应 backend 容量时不领取 task,避免本地形成不可控积压。
- 每个 executor 只执行一个 task,完成后销毁。
- SPIFFE 身份从实际领取的 task 的 repository 和 job name 派生,不需要 queued 与
in-progress webhook 的二阶段关联。
- scheduler 的 runner registration credential 不进入 executor;executor 只得到执行
当前 task 所需的短期 lease/capability。
- task ACK、心跳和结果必须能够跨 scheduler 重启恢复;NATS 可以继续作为内部 handoff,
但不是 Gitea 任务事实来源。
- Pod 与 VM 共享 task/executor 协议,只有环境创建和销毁实现不同。
## 实现顺序
1. 固定当前 Gitea 版本所使用的 RunnerService protobuf 与 act_runner 版本,记录兼容
范围并建立协议契约测试。
2. 实现只注册、Declare labels 和容量感知 FetchTask 的 scheduler spike,暂不执行
task。
3. 从 act_runner 提取或复用 task 执行与日志上报能力,定义 scheduler 到 executor 的
单任务协议。
4. 首先接入 Pod executor,验证成功、失败、取消、超时和 scheduler 重启。
5. 接入 microVM executor,并复用同一 task 协议和身份派生逻辑。
6. 双轨运行并验证后,移除 webhook receiver、临时 runner 注册和 identity binding
subject。
## Bootstrap 实现的退出条件
只有同时满足以下条件才能删除 webhook 路径:
- scheduler 能通过 RunnerService 稳定领取并执行 Pod/VM task;
- Gitea UI 中的实时日志、取消、超时和结论与官方 runner 行为一致;
- scheduler 重启不会丢失已领取 task,也不会重复执行;
- SPIFFE 身份只来自实际领取 task;
- 同一套 workflow 无需修改 `runs-on` 即可从 bootstrap 迁移。
