The MIN_INFERENCE_THREADS, MAX_INFERENCE_THREADS, and inference_thread_count() defined in constants.rs were superseded by the equivalents in tuning.rs (Task 2.1) and are no longer called by any production code. Both call sites (whisper backend Task 4.1, LLM generate Task 5.1) have migrated. Constants.rs now holds only audio/mel/RAM/VAD/download constants; inference-tuning concerns live in tuning.rs.
