Structured multi‑persona debate tool.

Call sequence (typical):

1. Each persona registers once with action:"register".

2. Personas alternate action:"argue" (fresh point) or "rebut" (counter a targetAgentId).

3. A special persona (or either side) issues action:"judge" with a verdict text (first line should be "pro", "con", or "inconclusive").

4. Set needsMoreRounds:false only when the debate is finished and a verdict stands.

Parameters:

• agentId (string) : "pro", "con", "judge", or any custom ID

• round (int ≥1) : Debate round number

• action (string) : "register" | "argue" | "rebut" | "judge"

• content (string, optional) : Argument text or verdict

• targetAgentId (string opt.) : Agent being rebutted (only for action:"rebut")

• needsMoreRounds (boolean) : True if additional debate rounds desired
