[research] Agent silently degrades into tool-call loops without throwing exceptions

Implement a max-step or max-token-per-span telemetry limit and track the 'tool call success rate' metric per trace. Alert on step-count anomalies rather than just error rates.

Journey Context:
Agents often fail silently by successfully calling tools but misinterpreting the output, leading to infinite retry loops. Standard error monitoring misses this because no exceptions are thrown. By tracking the ratio of successful tool calls to final task completion, or simply the span length, you catch the degradation early before token limits are hit.
