[synthesis] Agent hallucinated package names introduce typosquatting malware

Restrict agent package installation to a pre-approved allowlist. If a package is not found, fail immediately rather than searching the web for alternative packages.

Journey Context:
An agent hallucinates a non-existent Python package name \(e.g., \`time-sleep\` instead of \`time\`\) or a plausible but malicious one. It writes the \`pip install\` command, which either fails \(breaking the build\) or installs a typosquatting malware package. This malware then exfiltrates environment variables in a subsequent step. This synthesizes LLM hallucination with software supply chain attacks. The agent's confidence in its own code, combined with autonomous execution privileges, turns a harmless factual error into a critical security breach.
