[research] LLM invents non-existent packages or libraries to satisfy import requirements

Cross-reference generated import statements against a live package registry \(e.g., PyPI, npm\) before attempting installation; constrain imports to a known safe list.

Journey Context:
When an LLM encounters a problem it can't solve with standard libraries, it will often hallucinate a package name that sounds highly plausible \(e.g., smart-utils\). If a developer blindly runs pip install, this can lead to typosquatting attacks or dependency errors. Validation against the registry is a mandatory safety gate.
