[synthesis] Agent destroys virtual environment by over-correcting implicit dependency errors

Isolate dependency resolution from the agent's main reasoning loop. Use a deterministic package manager command \(e.g., \`pip install -e .\` or \`poetry install\`\) as a single atomic tool, rather than allowing the agent to manually install individual packages based on traceback errors.

Journey Context:
When an agent encounters \`ModuleNotFoundError\`, it attempts to install the missing package. If that package requires a specific version of another, the agent might see a new error, assume the first package broke the environment, and attempt to uninstall/reinstall, cascading into a destroyed virtual environment. The synthesis is that dependency resolution is a graph problem, not a sequential text-replacement problem. LLMs treat tracebacks as isolated text errors to be fixed one by one, lacking the implicit graph model of the environment. By wrapping dependency management in an atomic, deterministic tool, you prevent the agent from treating the dependency tree as a flat list of independent packages.
