目标

创建 packages/daemon/src/worker-runtime.ts，实现通用进程管理原语。

变更范围

  • 新增 worker-runtime.ts
  • 吸收 worker-fork-support.ts 的通用逻辑（stderr capture, exit summary）

具体任务

  1. 实现 ManagedWorker：fork → ready → draining → stopped 状态机
  2. 实现 WorkerRuntime<K>：按 key 管理多个 ManagedWorker
  3. 功能：cold start, send, crash respawn with backoff, drain+respawn, graceful shutdown
  4. 单元测试（不需要 sense/workflow 上下文）：
    • cold start: send 时自动 fork
    • crash respawn: worker 挂了自动重启
    • crash limit: 连续崩溃超限停止重试
    • drain: shutdown + 自动 respawn
    • evict: shutdown 不 respawn
    • shutdown all: 全部关闭

验证步骤

  • WorkerRuntime 类型导出
  • 基本状态转换测试通过
  • crash backoff 测试通过
  • drain + respawn 测试通过
  • pnpm run build + pnpm test 通过
  • 不影响现有 sense/workflow 逻辑（纯新增文件）
