"""后端 / CLI / DB 单元测试入口（unittest，不强制 pytest）。

用法：
    python tests/run_tests.py              # 发现 tests/ 根目录下全部 test_*.py
    python tests/run_tests.py -v           # 详细输出
    python tests/run_tests.py cli_smoke    # 仅匹配 test_cli_smoke.py
    python tests/run_tests.py test_cli_smoke

说明：
    只发现本目录（tests/）下一层的 test_*.py；不递归 ``samples/``、``integration/``、
    ``desktop/``（后三者提供 ``*.sample`` 或 pytest 专用用例，见 ``tests/README.md``）。
