The tool-use nudge fired on every first response without tools, even
when the conversation already had tool results the AI could reference.
This forced the AI to make a new (broader) tool call instead of
interpreting a short follow-up like "2026-02-11" in context of the
prior exchange. Now the nudge only fires when there are no prior tool
results in the conversation. Also added a system prompt rule telling
the AI to interpret ambiguous follow-ups in context.
