Overall this looks great added some comments mainly around configurability but logic itself looks good.
The logs are super useful thanks for adding them

let's make this a single JSX string instead of multiple and make this a function in a utils file taking in the data as params that way if we have other scaling tests we can reference this
| console.log('Starting Agent Scalability Analysis'); | ||
| console.log(`Log file: ${mainLogFile}`); | ||

same here re making this a util

| // Check if this is a breaking point (high error rate or very slow responses) | ||
| if (metrics.errorCount > 0.2 * metrics.messagesSent || |

This is a great addition - let's make these thresholds configurable / easier to discern by making this a constant and also consider running the load tests 3 with 3 different configurations of it i.e. with 3 thresholds like HIGH, MED, LOW and thresholds configured accordingly. That way in a single run we can see BREAKING POINT IDENTIFIED WITH HIGH THRESHOLD(details of thresholds), BREAKING POINT IDENTIFIED WITH MID THRESHOLD (details) , BREAKING POINT IDENTIFIED WITH LOW THRESHOLD (thresholds) lmk if you have any questions

let's make this configurable

Issue #397.1:Load Testing Agents at Scale
Risks
Low. This PR introduces load testing infrastructure that simulates high volumes of concurrent agent interactions. Risks include:
Background
What does this PR do?
Implements a load testing framework to simulate agent interactions in social environments at various scales (2-1000+ agents). The system measures performance metrics, stability, and error rates to determine system breaking points and scalability thresholds.
What kind of change is this?
Features (non-breaking change which adds functionality)
Documentation changes needed?
My changes require a change to the project documentation to explain how to run and interpret load tests.
Testing
Where should a reviewer start?
