fix: seed 参数只传给 LocalExecutor，假执行器/CloudExecutor 旧签名不再炸

worker 曾无条件给同步路径的 goal_task/dispatch_task 传 seed_dir，
CloudExecutor 基类与测试假执行器只有 (task) 一个参数，直接
TypeError，炸掉 test_project_repo 2 个 + test_cloud_executor_goal_unsupported
1 个（后者本应报“不支持 goal”）。改成 isinstance(LocalExecutor)
才传 seed_dir，其余走原签名；Docker 路径已有 is_docker 守卫。
