[synthesis] Agent confidently makes catastrophic dependency changes to fix a superficial error that matches a common training pattern

Implement a 'dependency mutation cooldown' or require explicit root-cause justification before allowing changes to core dependency files \(e.g., package.json, requirements.txt\), forcing the agent to search the codebase for the actual missing import path first.

Journey Context:
When an agent sees ModuleNotFoundError, its high-frequency training data strongly associates this with pip install. It will confidently install the package, even if the real error was a typo in an import statement or a missing sys.path injection. This cascades into dependency hell. The agent is confidently wrong because the immediate action perfectly matches the error signature, but ignores the specific project context. Restricting dependency mutations forces deeper contextual search.
