Feat/body language

[jwgcurrie]

• Speak LLM replies through ALAnimatedSpeech in the body-language mode set by the optional body_language key in llm.json (disabled, random or contextual), falling back to ALTextToSpeech if the call fails; each LLMTurn records the mode and the path used.
• Log every NAOqi event from the PepperBox stream to the session log as NAOqiEvent, with EventStreamRestored and EventStreamLost marking where the record is complete.
• Remove the config hash test that the model identity test replaces.
