[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\`, ensuring Python recognizes the package context for relative imports.

Journey Context:
A developer has a package structure \`src/myapp/utils.py\` that contains \`from . import config\`. When they run \`python src/myapp/utils.py\` directly, the interpreter sets \`\_\_name\_\_\` to \`\_\_main\_\_\` and does not recognize the file as part of a package, causing relative imports to fail because there is no parent package context. The developer checks \`sys.path\` and sees the script directory is added, but the import still fails. Switching to \`python -m myapp.utils\` from the parent directory \(where \`myapp\` is importable\) sets the correct package context, allowing the relative import to resolve because Python treats the module as part of the \`myapp\` package rather than a standalone script.
