- Normalize stt.groq.language: cast to str, strip, treat empty/whitespace as unset (parity with xAI's str().strip()). - Clarify "blank = auto-detect" inline comments in 4 docs/configs to reflect the env-var fallback (HERMES_LOCAL_STT_LANGUAGE). - Document that HERMES_LOCAL_STT_LANGUAGE also drives the local faster-whisper provider, not just the CLI fallback. - Add unit tests covering: omitted language when unset, config-supplied language, env fallback, config-over-env precedence, whitespace normalized to unset.
