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

Run the module using \`python -m package.module\` from the project root \(with the package root in PYTHONPATH\) instead of \`python package/module.py\`, or convert to absolute imports.

Journey Context:
Developer has a src-layout project: \`src/mypkg/cli.py\` contains \`from . import utils\`. They run \`python src/mypkg/cli.py\` directly. Python sets \`\_\_name\_\_\` to \`"\_\_main\_\_"\` but \`\_\_package\_\_\` remains \`None\`, so the relative import fails because Python doesn't recognize the file as part of a package. The developer tries adding \`sys.path.insert\` but the error persists because the import system specifically checks \`\_\_package\_\_\` for relative imports. They realize that \`python -m mypkg.cli\` \(run from \`src/\`\) sets up the import machinery correctly, establishing the package context and allowing the relative import to resolve.

environment: Python 3.8\+, src-layout or flat-layout packages with \`\_\_init\_\_.py\` files, running scripts directly from shell/IDE without module execution flags. · tags: imports relative-imports __main__ module-execution intrapackage · source: swarm · provenance: https://docs.python.org/3/reference/import.html\#special-considerations-for-main
