bump version to 0.3.0

本次提交更新了版本号至0.2.13，同时完成多项改进：
1.  在.gitignore中新增忽略性能分析文件*_profile.html
2.  修复测试用例中echo命令在Windows下无法被正确检测的问题，改用python命令
3.  优化测试用例确保性能统计数据有效，添加耗时模拟函数
4.  为所有CLI任务统一配置项目根目录作为工作目录，解决跨平台执行路径问题
5.  新增测试验证所有任务的cwd配置正确性

+# Python 开发规范
+
+本规范结合 Python 最佳实践，作为编写与审查 Python 代码的统一标准。
+详细操作指南见 `.agents/skills/` 下相应技能。
+
+## 工具链（以 pyproject.toml 为准）
+
+| 工具 | 用途 | 配置要点 |
+|------|------|---------|
+| **ruff** | lint + format | `line-length=120`，`target-version="py38"` |
+| **pyrefly** | 类型检查 | `preset="strict"`，`python-version="3.8"` |
+| **pytest** | 测试 | `asyncio_default_fixture_loop_scope="function"`，marker `slow` |
+| **coverage** | 覆盖率 | `branch=true`，`fail_under=95`，`concurrency=["thread"]` |
+| **pre-commit** | 提交前检查 | ruff `--fix` + trailing-whitespace + end-of-file-fixer |
+
+验证（每次修改后必做）：
+
+```bash
+uvx --from pyflowx pymake tc
+uvx --from pyflowx pymake cov
+```
+
+## 兼容性
+
+- **最低 Python 3.8**：用 `from __future__ import annotations` 延迟注解求值；
+  按版本用 `typing.List`(3.8) → 内置泛型(3.9) → `X | Y`(3.10) → `typing.override`(3.12)。
+- **版本守卫**：`if sys.version_info >= (3, X):` 引入高版本 API；低版本回退分支加 `# pragma: no cover`。
+- **零运行时依赖**：仅依赖标准库（3.8 需 `graphlib_backport`、`typing-extensions`）。
+  新增依赖须审慎，优先用标准库。
+
+## 类型注解
+
+- **公共 API 必须有完整类型注解**，包括返回类型；私有函数也应有注解。
+- 泛型用 `TypeVar`；PEP 696 `default=` 仅 3.13+ 标准库支持，3.8–3.12 用 `typing_extensions.TypeVar`。
+- `Mapping`/`Sequence` 用于只读参数，`dict`/`list` 用于可变返回。
+- `Any` 仅用于真正动态场景（如 `Context` 跨任务异构映射）；任务内部类型必须完全静态。
+- 禁用裸 `# type: ignore`；确需时加具体规则码（如 `# type: ignore[union-attr]`）。
+- **`TYPE_CHECKING` 守卫**：仅类型检查需要的导入放 `if TYPE_CHECKING:` 块内，避免循环依赖。
+- **类型收窄**：用 `assert isinstance(x, Y)` 辅助 pyrefly 推断；`cast()` 仅用于类型系统无法表达的场景。
+
+## 数据结构
+
+- **不可变优先**：配置/描述类用 `@dataclass(frozen=True)`；可变类属性标注 `RUF012` 豁免。
+- **缓存**：实例级用 `functools.cached_property`，按参数键控用 `functools.lru_cache`；
+  不可哈希参数需 try/except 回退。修改被缓存数据源后必须手动清空缓存。
+- **抽象基类**：接口用 `abc.ABC` + `@abstractmethod`（如 `StateBackend`）。
+- **枚举**：状态/标志值用 `enum.Enum`（如 `TaskStatus`），禁止裸字符串/魔术数字；枚举值用 `UPPER_SNAKE`。
+- **`__repr__`**：可变类实现 `__repr__`（含关键字段）；`frozen=True` dataclass 自动生成。
+
+## 模块与导入
+
+- **单一职责**：每模块只做一件事（`task.py` 数据结构、`executors.py` 执行、`command.py` 命令、`compose.py` 组合）。禁止跨职责边界。
+- **导入顺序**（ruff isort）：`__future__` → 标准库 → 第三方 → 本地，各组间空行。
+- **惰性导入**：仅为打破循环依赖时使用，函数体内导入并注释说明；顶层导入是默认。
+- **`__all__`**：定义 `__all__` 显式声明导出符号，位置仅次于 `__future__` 之后。
+- **禁用 star imports**：`from x import *` 污染命名空间、破坏类型检查（`__init__.py` 聚合经 `__all__` 控制为例外）。
+- **避免 `utils.py`/`helpers.py`**：按职责归入对应模块。
+
+## 函数设计
+
+- **模块级函数优于 Mixin**：共享逻辑用模块级函数，类只持有状态与薄方法。
+- **静态方法慎用**：纯函数直接放模块级。
+- **参数 ≤ 5 个**为宜；超出用 dataclass 封装参数对象。
+- **单一职责**：一个函数做一件事；过长函数考虑拆分。
+- **异常范围要窄**：只捕获预期异常（如 `(TypeError, ValueError, KeyError, AttributeError)`），
+  **禁止** `except Exception` 掩盖 bug；捕获后至少 `logger.warning` 记录。
+- **可变默认参数**：`def f(x=[])` 是经典坑；用 `None` 哨兵或 `field(default_factory=list)`。
+
+## 异常处理
+
+- **自定义异常家族**：继承公共基类（如 `PyFlowXError`），按错误场景分类。
+- **异常包装**：`raise NewError(...) from exc` 保留因果链。
+- **不要吞异常**：捕获后必须处理（记录/包装/重抛），禁止空 `except: pass`。
+- **钩子/回调异常**：第三方回调异常仅记录，不影响主流程。
+
+## 并发与线程安全
+
+- **进程全局状态**（`os.environ`/`os.chdir`）在并发场景下必须用全局锁（`threading.RLock`）序列化。
+- **条件评估不可有可变状态**：组合条件（NOT/AND/OR）不得修改共享 `_reason`，避免竞态。
+- **批量 I/O**：循环内多次写盘改为批量一次（`contextmanager` 包裹延迟落盘）。
+- **信号量限流**：`concurrency_key` + `Semaphore` 按组限流。
+
+## 测试
+
+详细操作指南见 `.agents/skills/pyflowx-testing` 技能。硬约束：
+
+- **覆盖率 ≥ 95%**（branch coverage），不得下降。
+- **公共 API 优先测试**：用公共接口（`has`/`get`），不访问私有方法；
+  故障注入等场景可临时访问私有属性，docstring 注明原因。
+- **命名**：`test_<被测对象>_<场景>`。
+- **断言**：原生 `assert x == 1`，禁用 `self.assertEqual`；`pytest.raises` 必填 `match=`。
+- **Mock 优先级**：`monkeypatch` > 内联 stub > `unittest.mock` > `pytest-mock`。
+  禁用 `@patch` 装饰器、`mock.patch.object` 上下文、`pytest-mock` 的 `mocker` fixture。
+- **fixture**：`tmp_path`/`monkeypatch`/`capsys` 优先；autouse 仅全局必需时用。
+- **slow 标记**：耗时测试加 `@pytest.mark.slow`，CI 可 `-m "not slow"` 跳过。
+- **测试代码也跑 ruff**：`tests/**` 忽略 `ARG001`/`ARG002`。
+
+## 代码风格
+
+- **行宽 120**（ruff formatter 处理）。
+- **docstring**：公共 API 必须有；中文叙述 + 中文注释是本项目既有风格。
+- **打印和日志**：使用中文打印和日志，避免使用英文。
+- **命名**：`snake_case` 函数/变量，`PascalCase` 类，`UPPER_SNAKE` 常量，`_leading_underscore` 私有。
+- **字符串引号**：ruff 默认双引号。
+- **末尾单 `\n`**、**无尾随空格**（pre-commit 强制）。
+- **不用 emoji**：除非用户明确要求。
+
+## Pythonic 风格
+
+- **`is` 比较 `None`/`True`/`False`**：单例用 `is`，值用 `==`（PEP 8 E711/E712）。
+- **EAFP 优于 LBYL**：先尝试再处理异常，而非先检查再执行（避免竞态窗口）。
+- **truthiness**：`if items:` 优于 `if len(items) > 0:`。
+- **字符串格式化**：首选 f-string；`%` 仅用于 `logging` 延迟格式化。
+- **推导式**优于 `map`+`filter`；> 2 层拆为显式循环。
+- **`enumerate`** 替代 `range(len())`；**`zip`** 并行迭代（3.10+ 用 `strict=True`）。
+- **解包** `a, b = pair` 优于索引访问；忽略值用 `_`。
+- **海象运算符 `:=`**（3.8+）：赋值+判断合一，但不滥用。
+
+## 日志
+
+- **`logging.getLogger(__name__)`**：每模块独立 logger，禁用 `print` 调试残留。
+- **结构化上下文**：`extra={...}` 传字段；`logger.warning("task %r failed: %s", name, exc)` 优于 f-string（延迟格式化）。
+- **日志级别**：`DEBUG` 诊断 / `INFO` 关键流程 / `WARNING` 可恢复异常 / `ERROR` 需人工介入。
+- **禁止日志密码/密钥**：脱敏后再记录。
+
+## 路径与资源
+
+- **优先 `pathlib.Path`**：`Path("a") / "b"` 而非 `os.path.join`（ruff `PTH` 强制）；
+  禁止字符串拼接路径。类型注解用 `Path`，边界 `str` 立即包装。
+- **`with` 语句**：文件、锁、连接、临时目录一律用 `with` 或 `contextlib.contextmanager`；
+  多资源用 `contextlib.ExitStack`。
+- **显式关闭**：长生命周期对象（连接池、线程池）实现 `close()`，但优先 `with`。
+- **批量操作**：循环内多次 acquire/release 改为批量一次。
+
+## 安全
+
+- **禁用 `eval`/`exec`**：处理不可信输入时绝不使用；用 `ast.literal_eval` 或专用解析器。
+- **`subprocess`**：禁用 `shell=True` 除非命令完全可信；优先 `list[str]` 形式。
+- **凭证不入仓**：密钥/token/密码放 `.env` 或环境变量，`.gitignore` 必须包含 `.env`。
+- **日志脱敏**：记录请求/响应时移除 `Authorization`、`password` 等字段。
+- **依赖审计**：`uv lock` 后审阅新增依赖，避免引入已知 CVE 的包。
+
+## 性能要点
+
+- **避免重复计算**：循环内查询应缓存或预构建映射（如 `{name: spec}`）。
+- **避免双重查找**：`has(k)` + `get(k)` 改为单次 `get(k)` + `KeyError` 回退。
+- **统一校验**：入口校验一次，下游路径不重复（如 `run()` 统一 `validate()`，`layers()` 不再重复）。
+- **事件 emit**：任务生命周期必须 emit `RUNNING` → `SUCCESS`/`FAILED`/`SKIPPED`，
+  不要留死分支（`# pragma: no cover` 是清理信号，应激活或删除）。
+
+## Git 与提交
+
+- **不自动提交/push**：除非用户明确要求。
+- **不修改 git config**。
+- **不运行破坏性命令**（`push --force`/`reset --hard`/`clean -f`）除非用户明确要求。
+- **staging**：按文件名添加，不用 `git add -A`/`git add .`，避免误加敏感文件。
+- **commit message**：简洁，聚焦"为什么"而非"是什么"；遵循仓库既有风格。

+---
+
+# PyFlowX 测试规范
+
+本技能是 `.trae/rules/python-standards.md` 测试章节的详细展开。
+规则文件仅保留硬约束指针，本文件提供完整操作指南。
+
+## 总则
+
+- **覆盖率 ≥ 95%**（branch coverage），不得下降。
+- **公共 API 优先测试**：测试用公共接口（`has`/`get`），不访问私有方法
+  （如 `_expired`）。兼容旧测试的私有方法应删除并迁移测试。
+  例外：`_store`/`_flush` 等内部状态在无法用公共 API 触发时（如模拟过期、
+  故障注入），可临时访问私有属性，并在 docstring 注明原因。
+- **命名**：`test_<被测对象>_<场景>`，如 `test_storage_key_cache_key_exception_returns_name`。
+- **每个测试一个断言重点**；多个断言要语义相关。
+- **slow 标记**：耗时测试加 `@pytest.mark.slow`，CI 可 `-m "not slow"` 跳过。
+- **测试代码也跑 ruff**：`tests/**` 忽略 `ARG001`/`ARG002`（未用 fixture 参数）。
+- **断言风格**：用原生 `assert` + 比较运算符（`assert x == 1`），
+  不用 `self.assertEqual`；pytest 会生成更清晰的 diff。
+
+## Mock 工具选择（强制）
+
+**优先级**：`monkeypatch` > 内联 stub > `unittest.mock` > `pytest-mock`。
+
+| 场景 | 工具 | 示例 |
+|------|------|------|
+| 替换模块属性 / 环境变量 / 工作目录 | `monkeypatch` | `monkeypatch.setattr(subprocess, "run", fake_run)` |
+| `os.environ["KEY"]` 临时设置 | `monkeypatch.setenv` | `monkeypatch.setenv("LOCALAPPDATA", "C:\\...")` |
+| 切换 cwd | `monkeypatch.chdir` | `monkeypatch.chdir(tmp_path)` |
+| 一次性 stub 函数 | 内联 lambda / 闭包 | `ran = []; monkeypatch.setattr(subprocess, "run", lambda *c, **__: ran.append(c))` |
+| 复杂 spy（记录调用次数/参数/返回序列） | `unittest.mock.MagicMock` | 仅当 lambda 不足以表达时 |
+| `with patch(...)` 上下文 | **禁用**（用 monkeypatch） | monkeypatch 自动 teardown 更安全 |
+
+**禁止**：
+- 不用 `pytest-mock` 的 `mocker` fixture（项目虽在 dev 依赖声明，但实际
+  测试代码未使用；为保持风格统一，新代码继续用 `monkeypatch`）。
+- 不用 `unittest.mock.patch` 装饰器（`@patch("x.y")`），它隐藏依赖且
+  与 pytest fixture 模式不兼容；用 `monkeypatch.setattr` 替代。
+- 不用 `mock.patch.object` 作为上下文管理器，除非被测代码本身就是
+  contextmanager（此时用 `monkeypatch.setattr` 仍更简单）。
+
+## monkeypatch 使用规范
+
+- **类型注解**：fixture 参数标注 `monkeypatch: pytest.MonkeyPatch`。
+- **作用域**：monkeypatch 自动在测试结束时撤销，**禁止**手动
+  `monkeypatch.setattr(x, "y", original)` 恢复（多余且容易遗漏）。
+  例外：在单个测试内需要中途恢复时，用 `monkeypatch.undo()` 全量撤销。
+- **替换目标**：替换"被测代码看到的对象"，而非全局对象本身。
+  - 错误：`monkeypatch.setattr("os.path.exists", fake)` —— 替换全局，影响其他模块。
+  - 正确：`monkeypatch.setattr(pyflowx.command.shutil, "which", fake)` ——
+    替换被测模块引用的 `shutil.which`。
+- **属性 vs 字符串路径**：优先属性访问形式 `monkeypatch.setattr(obj, "attr", val)`
+  而非字符串路径 `monkeypatch.setattr("pkg.mod.obj.attr", val)`，
+  前者有 IDE 跳转与重构支持。
+- **记录调用**：用闭包 `ran: list[tuple] = []` + `lambda *a, **k: ran.append((a, k))`
+  替代 `MagicMock`，可读性更好且无需导入。
+
+## Stub 与 Spy 模式
+
+- **轻量 stub**：内联定义 `class MockResult: returncode = 0; stdout = ""`，
+  替代 `MagicMock(return_value=...)`，类型明确且不引入 mock 依赖。
+- **状态收集**：闭包 + list 比 `mock.call_args_list` 更易断言：
+  ```python
+  calls: list[list[str]] = []
+
+
+  def fake_run(cmd: list[str], **_: Any) -> MockResult:
+      calls.append(cmd)
+      return MockResult()
+
+
+  monkeypatch.setattr(subprocess, "run", fake_run)
+  assert calls == [["clear"]]
+  ```
+- **副作用序列**：需要按调用次数返回不同值时，用 `itertools.cycle` 或
+  手动计数器，而非 `side_effect=[...]`（mock 专有 API）。
+- **异常注入**：`def raise_oserror(*a, **k): raise OSError("...")`，
+  用 `pytest.raises(OSError)` 验证，而非 `side_effect=OSError`。
+
+## 异常断言
+
+- **`pytest.raises`**：必填 `match=` 正则（除非异常消息完全不可预测），
+  避免误捕获同类异常：
+  ```python
+  with pytest.raises(StorageError, match="cannot write"):
+      b.save("a", 1)
+  ```
+- **异常链**：验证 `__cause__` 时用 `exc_info.value.__cause__`，
+  确认 `raise X from Y` 因果链完整。
+- **禁止** `try/except + assert False`：用 `pytest.raises` 替代。
+
+## Fixture 规范
+
+- **`tmp_path`**：处理临时文件，自动清理，禁止 `tempfile.mkdtemp()` 手动管理。
+- **`monkeypatch`**：环境变量、cwd、模块属性 mock（见上）。
+- **`capsys`/`capfd`**：捕获 stdout/stderr，验证日志或命令输出。
+- **autouse fixture**：仅在全局必需时用（如 `conftest.py` 的
+  `packtool_tmp_workdir` 自动切到 tmp_path）；否则显式声明参数。
+- **fixture 命名**：`snake_case`，描述"提供什么"而非"测试什么"
+  （`sample_graph` 优于 `test_data`）。
+- **fixture 作用域**：默认 `function`；`module`/`session` 仅当构造昂贵且
+  只读时，并加注释说明无副作用。
+
+## asyncio 测试
+
+- **fixture `loop_scope="function"`**（pyproject 已配置默认值）。
+- **async 测试**：`async def test_x():`，pytest-asyncio 自动驱动。
+- **await 检查**：测试异步函数必须 `await` 结果，禁止仅验证返回 coroutine 对象。
+- **异步 mock**：用 `AsyncMock`（3.8+ 在 `unittest.mock`）或
+  `async def fake(): return value`，禁用 `MagicMock(return_value=coro)`。
+
+## 参数化
+
+- **`@pytest.mark.parametrize`**：用 `ids` 参数提供可读标识：
+  ```python
+  @pytest.mark.parametrize(
+      ("strategy", "expected_workers"),
+      [("sequential", 1), ("thread", 8), ("async", 1)],
+      ids=["seq", "thread-8", "async"],
+  )
+  ```
+- **参数命名**：参数元组用有意义名称，而非 `("a", "b")`。
+- **组合爆炸**：参数组合 > 20 时拆分测试，避免单个测试函数臃肿。
+
+## 测试组织
+
+- **文件命名**：`test_<被测模块>.py`（`test_storage.py` 对应 `storage.py`）。
+- **类分组**：仅在测试逻辑强相关时用 `class TestXxx:` 分组；默认用模块级函数。
+- **docstring**：每个测试函数一句话说明"测试什么场景"，复杂场景补充"为什么"。
+- **setup/teardown**：优先 fixture；`setup_method`/`teardown_method` 仅在
+  无法用 fixture 表达时（罕见）。

+"""pxp —— PyFlowX 性能分析器.
+
+分析包含 ``px`` 调用的 Python 脚本，生成工作流执行性能剖面报告。
+
+工作原理
+--------
+1. 注入 hook：monkey-patch ``pyflowx.run`` / ``pyflowx.executors.run`` /
+   ``pyflowx.runner.run``，捕获最后一次执行的 ``Graph`` 与 ``RunReport``。
+2. 执行目标脚本：用 ``runpy.run_path`` 以 ``__main__`` 身份执行，
+   捕获 ``SystemExit``（脚本可能调 ``sys.exit``）。
+3. 生成报告：从捕获的 report + graph 构建 :class:`ProfileReport`，
+   默认输出 HTML 并自动打开浏览器。
+
+使用方式
+--------
+    # 分析 pymake.py，生成 HTML 报告并打开浏览器
+    pxp pymake.py
+
+    # 传递参数给被分析脚本（用 -- 分隔）
+    pxp pymake.py -- t
+
+    # 指定输出文件
+    pxp pymake.py -o report.html

+* **图级**：总耗时（wall-clock）、关键路径耗时（理论最短耗时）、
+  并行度效率（关键路径耗时 / 总耗时）。
+* **关键路径**：从源点到汇点的最长依赖路径，识别真正的串行瓶颈。
+* **并行度**：基于时间线重叠计算瞬时并行度，给出平均并行度与峰值并行度。
+* **瓶颈识别**：按耗时排序的 Top-N 任务。
+
+设计原则
+--------
+* 数据来源于 ``RunReport`` + ``Graph``，无副作用。
+* 计算复杂度 O(V+E)：拓扑排序 + 单次松弛，适合大规模图。
+* 所有时间戳用 ``datetime``，与 :class:`TaskResult` 保持一致。

 执行器向后端查询某任务是否已有存储结果；若有则跳过该任务，并将其

-本模块刻意保持最小化：仅持久化*成功*结果（失败任务会重跑），存储
-形态为扁平的 ``{task_name: result}`` 映射。内置两个后端：
+存储键由 :meth:`TaskSpec.storage_key` 计算，默认为任务名；若任务配置
+了 ``cache_key``，则键为 ``"name:cache_key_value"``，使不同输入产生
+独立缓存条目。
 
-* :class:`MemoryBackend` —— 快速、进程内、无 I/O。默认。
-* :class:`JSONBackend` —— 持久化到 JSON 文件，支持跨进程续跑。
-
-两者均零依赖（``json`` 为标准库）。用户可子类化
-:class:`StateBackend` 接入 SQLite、Redis 等。

+    soft_depends_on:
+        软依赖任务名。会等待其完成，但其结果不影响本任务是否执行：
+        - 上游成功：注入其返回值
+        - 上游 SKIPPED 或失败：注入 :attr:`defaults` 中提供的默认值
+        适用于"可选输入"场景。
+    defaults:
+        软依赖的默认值映射 ``{dep_name: default_value}``。
+        软依赖未提供结果时使用。未在 defaults 中出现的软依赖默认为 ``None``。
     args:
-        静态位置参数，追加在注入参数*之后*。适用于参数化任务
-        （如 ``fetch_user(uid)``）。
+        静态位置参数，追加在注入参数*之后*。
     kwargs:
         静态关键字参数。若与注入名冲突则抛出
         :class:`~pyflowx.errors.InjectionError`。
-    retries:
-        失败后的重试次数。``0`` 表示仅尝试一次。
+    retry:
+        :class:`RetryPolicy` 重试策略。默认仅尝试一次。
     timeout:
         最大执行时长（秒）。``None`` 表示不限制。异步任务使用
-        :func:`asyncio.wait_for`；线程/异步执行器中的同步任务会
-        取消 worker future。
+        :func:`asyncio.wait_for`；同步任务通过线程 future 取消。

     conditions:
-        条件判断函数列表，只有所有条件都返回 ``True`` 时才执行任务。
-        若任一条件返回 ``False``，任务会被标记为 SKIPPED。
-        用于平台判断、环境变量检查等场景。
+        条件判断函数列表，接收依赖上下文，全部返回 ``True`` 时才执行任务。
+        任一返回 ``False`` 则任务被标记为 SKIPPED。
     cwd:
-        命令执行的工作目录，仅在使用 ``cmd`` 参数时有效。
-        ``None`` 表示当前目录。
+        工作目录。对 ``cmd`` 任务作为子进程工作目录；对 ``fn`` 任务
+        通过临时切换当前目录生效。
+    env:
+        环境变量覆盖映射。对 ``cmd`` 任务合并到子进程环境；对 ``fn``
+        任务在执行期间临时设置。
     verbose:
-        是否在命令执行时显示详细输出。``True`` 时会打印执行的命令
-        及其标准输出/标准错误。仅在使用 ``cmd`` 参数时有效。
-        ``False`` 时静默捕获输出（失败时仍会包含在错误信息中）。
+        是否打印详细输出。``True`` 时打印执行的命令、返回码与输出
+        （仅 ``cmd``），以及任务生命周期。
     skip_if_missing:
-        仅对 ``cmd`` 为 ``list[str]`` 的任务有效。``True`` 时自动检查
-        命令是否存在（通过 :func:`shutil.which`），不存在则跳过任务
-        （标记为 SKIPPED）而非失败。适用于构建工具场景，避免因未安装
-        某些工具（如 maturin、tox）而导致整个图执行失败。
-        对于 ``str`` (shell) 和 ``Callable`` 类型的 ``cmd``，此参数无效。
+        仅对 ``cmd`` 为 ``list[str]`` 有效。``True`` 时通过

+    allow_upstream_skip:
+        若为 ``True``，硬依赖被 SKIPPED 时本任务仍执行（软依赖不影响）。
+        适用于清理类任务。
+    strategy:
+        单任务执行策略覆盖。``None`` 表示继承图级策略。
+        ``"sequential"`` 同步直接调用；``"thread"``/``"async"`` 将同步
+        任务卸载到线程池，异步任务跑在事件循环上。
+    priority:
+        同层任务调度优先级。数值越大越先启动。仅影响同层内启动顺序，
+        不打破层屏障。默认 ``0``。
+    concurrency_key:
+        并发限制分组键。具有相同键的任务共享一个信号量，限制同时
+        运行的实例数。具体限额由 :func:`run` 的 ``concurrency_limits``
+        参数提供 ``{key: limit}`` 映射。``None`` 表示不限制。
+    continue_on_error:
+        若为 ``True``，任务最终失败时不中止整图，仅标记本任务 FAILED，
+        其硬依赖下游被 SKIPPED，其余任务继续。默认 ``False``。
+    cache_key:
+        缓存键计算函数。若提供，则用其基于依赖上下文计算的字符串键
+        存取状态后端，使不同输入产生独立缓存条目。``None`` 表示用任务名。
+    hooks:
+        :class:`TaskHooks` 生命周期钩子。
+    executor:
+        同步任务的执行器：``"thread"``（默认，线程池）/ ``"process"``
+        （进程池，绕过 GIL，适合 CPU 密集型；``fn`` 须可 pickle）/
+        ``"inline"``（直接在事件循环线程调用，最快但会阻塞循环）。
