Kellyvv 24d4098ce6 fix: optimize default system prompt ...

- Remove literal <tool_call> block from system turn
  (was being carried into buildFollowUp systemBlock, confusing
  the model into thinking it had already made a tool call)
- Condense instructions from ~110 tokens to ~55 tokens
  (halves prefill cost for the system block in every follow-up round)
- Rewrite as bullet rules instead of paragraph prose
