CRITICALnpm lifecycle script — runs automatically on install

"test": "node --test tests/*.test.js",
"postinstall": "node -e \"console.log('\\\\n🧠 pūrmemo MCP ready! Run: npx purmemo-mcp setup\\\\n')\""
},Why was this flagged?
npm lifecycle scripts like postinstall run automatically during package installation with no user interaction required. This is the #1 attack vector for malicious npm packages — attackers embed data theft or backdoor installation in these hooks. Rated CRITICAL because code executes before the developer can review it.
