Report #75280

[research] Agent gets stuck in an infinite tool-calling loop, burning tokens and budget

Set hard limits on per-run token usage and tool call depth in the agent executor. Emit telemetry alerts when an agent retries the same tool more than twice with the same arguments.

Journey Context:
LLMs occasionally get stuck in loops, especially when an API returns an unexpected error format. Without observability into the loop and hard circuit breakers, a single runaway agent session can drain an API budget. Detecting 'same tool, same args' is a high-signal indicator of a stuck state.
