feat: replace runtime cog.yaml parsing with Dockerfile ENV vars, delete dead SDK modules Emit COG_PREDICT_TYPE_STUB, COG_TRAIN_TYPE_STUB, and COG_MAX_CONCURRENCY as ENV lines in the generated Dockerfile so the container never needs to parse cog.yaml at startup. http.py reads these env vars directly; coglet reads COG_MAX_CONCURRENCY from the environment instead of calling into Python config code. Delete config.py, errors.py, mode.py, and logging.py from the Python SDK as they are no longer imported by any remaining code.
