Fix agent status reset bug in stream_mode=values 

With stream_mode="values", each chunk contains the full accumulated state.
The debate and risk sections were checking data fields (bull/bear history,
aggressive/conservative/neutral history) without guarding against re-processing,
causing completed agents to be reset to "in_progress" on every subsequent
chunk. This made agent and report counts appear stuck at 5/12 and 4/7.

Fix: move the _emitted flag guard to the outer if-block so the entire
section is skipped once its event has been emitted.
