[research] Agent silently degrades by taking longer execution paths or looping without failing

Implement statistical trace-level monitoring on step count and execution duration distributions. Alert on distribution shifts \(e.g., P95 step count increasing\) rather than binary pass/fail.

Journey Context:
Agents often don't 'crash' when they degrade; they just loop or take suboptimal paths. Binary outcome evals miss this entirely. By tracking the distribution of steps/duration, you catch silent degradation before it becomes a token-cost crisis or timeout failure.
