error_engine.py

"""WatchDog Error Engine — Mutation layer for any environment.

Takes a clean player response from an environment (e.g. Avalon) and
optionally injects an error using the LLMMutator (Gemini / local LLM / template).

This module does NOT generate conversations — it only mutates them.
The environment plugin (e.g. AvalonGame) generates the clean turns.
