fix: describe local intent answers to the model instead of replaying them

With prefer_local_intents, Home Assistant puts requests its local intents
answered into the chat log as external calls of intents like
HassGetCurrentTime. The model does not have these tools, and replayed as
its own calls they make it apologise for using tools it does not have and
doubt answers it never gave. They are now passed as a developer note with
the intent, its arguments and its result.
