Report #96243

[gotcha] Denial of Service via recursive tool calls and infinite agent loops

Implement a hard limit on consecutive identical tool calls and a maximum total tool call depth per user turn in the orchestrator.

Journey Context:
LLMs are stateless and often stubborn. If a tool returns an error or unexpected result, the LLM might try the exact same arguments again, thinking it will work. Without an orchestrator-level circuit breaker, this continues until context limits or API credit limits are hit. The orchestrator must detect repetitive tool calls and halt the agent.
