Report #36288

[architecture] Two agents or an agent and a tool get stuck in an infinite loop of calling each other due to conflicting validation rules

Enforce a strictly monotonically decreasing step budget or token budget passed in the state object between agents. If the budget hits zero, force an exit or escalation.

Journey Context:
Agent A asks Agent B to fix code. Agent B returns code. Agent A tests it, fails, asks Agent B again. Agent B returns the same flawed code. Without a hard limit on state transitions, the loop runs forever, burning API credits. A step budget is a non-negotiable circuit breaker that prevents runaway compute costs in autonomous loops.
