By ensuring all modules are part of an importable package and are explicitly imported during the test run, we guarantee they are visible to the coverage tooling. +- **Implementation Details**: + - Created `src/cleveragents/providers/llm/__init__.py` to make the `langchain_chat_provider` part of a proper package. + - Added a new scenario to `features/architecture.feature` named "Every source module imports without errors". + - Implemented the corresponding step definitions in `features/steps/architecture_steps.py` using `pkgutil.walk_packages` and `importlib.import_module`. +- **Impact**: This enhances the robustness of our CI pipeline and ensures coverage metrics are accurate.
