变更摘要

本次变更将 DSL 框架的单元测试从“需要真实编译工具链的集成验证”收敛为纯逻辑回归：删除了在临时目录中重建 CMake 工程、伪造 Native/ACLNN runtime、调用编译器/链接器/nm/readelf 以及构建 wheel 的测试与辅助代码，仅保留针对发布缓存、回滚、资源归属和包结构校验的断言。三份测试文件均只涉及测试代码与导入的精简，未触及算子实现、CMake 脚本、CI 或发布 helper。

主要改动

• 简化 ACLNN 包校验 fixture：test_cannbotdsl_aclnn.py 中的 publish_aclnn 去掉了 mode 参数与全部 C++ 源码内容，改为按 l0/l2 开关只写入占位文件与 package.json manifest 所需路径，使包校验不再依赖可编译的 runtime。
• 删除 ACLNN 编译/链接/安装类测试：移除 aclnn_project 工程生成器、publish_native 以及 test_aclnn_build_link_and_install、test_dual_host_caches_are_independent_and_aclnn_runs_without_python、test_reconfigure_removes_only_unselected_host_path、test_separate_declaration_publishes_public_api_with_existing_asc_inner_registration、test_l2_declaration_changes_do_not_republish_native_or_device，并清理 ctypes、shutil、subprocess、Path 等导入；保留发布层级、缓存与 source_exports 标记识别相关用例。
• 移除 CMake 执行辅助与可选依赖构建测试：test_cannbotdsl_build.py 删除 cmake、build_install 辅助函数及 test_input_dependencies_preserve_cmake_paths，并移除 _optional_dsl_project 构建夹具与 test_real_unavailable_probe_still_builds_and_installs_asc、test_real_unavailable_probe_cleans_owned_stale_resources_and_keeps_asc、test_discoverable_modules_do_not_hide_real_dsl_build_errors；保留原子替换回滚与 sync_kernels 归属保护用例。
• 删除 wheel 打包回归测试：test_cannbotdsl_package.py 移除了基于 setup.py bdist_wheel 的 test_wheel_includes_recursive_dsl_sources_with_working_relative_imports，同时删除 os、shutil、subprocess、zipfile 导入，仅保留 custom Torch 包内相对导入的 test_custom_builder_loads_without_base_package。
