[bug\_fix] ImportError: attempted relative import with no known parent package

Execute the module using \`python -m package.module\` from the project root instead of \`python package/module.py\`. This sets \`\_\_package\_\_\` correctly, enabling the relative import resolution by treating the file as part of a package rather than a standalone script.

Journey Context:
You have a package structure with \`myapp/utils/helper.py\` containing \`from ..config import settings\`. You run \`python myapp/utils/helper.py\` directly to test it. It crashes with the relative import error. You check \`sys.path\` and see the script's directory added. You try adding \`if \_\_name\_\_ == '\_\_main\_\_': import sys; sys.path.insert\(0, os.path.dirname\(os.path.dirname\(os.path.abspath\(\_\_file\_\_\)\)\)\)\` which is fragile. You search the error and learn that direct execution sets \`\_\_name\_\_\` to \`\_\_main\_\_\` and \`\_\_package\_\_\` to None, breaking relative imports. You navigate to the project root and run \`python -m myapp.utils.helper\`. The script runs because Python treats it as a module within the package, \`\_\_package\_\_\` is set to \`myapp.utils\`, and the relative import \`..config\` resolves correctly to \`myapp.config\`.
