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

Implement a maximum iteration/step counter per agent run and emit a specific 'max\_steps\_reached' telemetry span, treating it as a hard failure in eval suites.

Journey Context:
Agents rarely crash with stack traces; they just keep calling tools that don't resolve the goal. Standard error monitoring misses this. By treating max\_steps\_reached as a first-class failure mode in observability, you catch the most common silent failure mode before it drains compute budgets.
