Report #14238

[research] Agent loops spiral out of control consuming tokens/cost without throwing an error

Implement observability circuit breakers based on token consumption and consecutive identical tool calls. Alert and halt the trace if the agent exceeds 80% of a predefined token budget or calls the same tool with the same arguments twice in a row.

Journey Context:
Agents can get stuck in loops \(e.g., repeatedly trying an API call that fails silently, or looping between two sub-agents\). Standard timeout limits are too coarse because the agent is actively doing work \(just useless work\). Token-based and repetition-based circuit breakers catch the semantic stuck state, not just the compute stuck state.
