[architecture] Infinite handoff loops between agents

Enforce a hard iteration limit on agent handoffs and implement a fallback mechanism to a supervisor or termination state when the limit is reached.

Journey Context:
LLMs lack global recursion awareness. When Agent A delegates to Agent B, and B lacks the context to resolve it, B often delegates back to A. Without a strict cutoff, this creates an infinite loop of tool calls or messages, burning tokens and stalling the system. This is the multi-agent equivalent of an infinite while loop and will happen reliably without external intervention.
