[research] LLM hallucinates non-existent package names or libraries in generated code

Provide the LLM with a verified manifest of available packages/dependencies in the system prompt, and run a static analysis linting step post-generation to check imports against the manifest before execution.

Journey Context:
When coding agents encounter a task requiring a library they don't perfectly recall, they confidently invent a plausible name \(e.g., 'python-docx-parser' instead of 'docx'\). This leads to supply-chain attacks if a malicious actor later registers that package, or simply runtime crashes. Prompting 'only use real packages' is insufficient. The agent must be grounded in an actual environment state \(the manifest\) and validated programmatically.
