Path as target

Support for scanning a --target directory instead of a virtual environment

[Copilot]

Pull request overview

Adds support for scanning a flat “target” directory (e.g., pip install --target <dir>) directly, instead of requiring a full virtual environment layout, by introducing a path_as_target flag on get_packages_from_env.

Changes:

• Extend get_packages_from_env with path_as_target to scan the provided directory directly (skipping venv layout, .pth, system, and PYTHONPATH discovery).
• Add unit tests covering target-directory scanning behavior and ensuring .pth/PYTHONPATH are ignored in this mode.
• Document the new target-directory scanning mode in the README.
