Pass LLM as a judge on the full transcript

Code Review Summary

I reviewed the code changes in this PR and found the implementation to be generally well-structured with comprehensive test coverage. The buildTranscript function correctly preserves temporal ordering of events for LLM evaluation.

However, I identified one issue with defensive programming consistency that should be addressed.

Unsafe type assertions that silently fail on malformed events

The getToolCallInfo function uses unchecked type assertions with the blank identifier _, which means it will silently return empty strings if the event structure is malformed:

tc, _ := event["tool_call"].(map[string]any)
fn, _ := tc["function"].(map[string]any)

While Go handles nil map access safely (won't panic), this produces confusing output like [Agent root calls tool "" with arguments: ] when events are malformed, instead of indicating a data problem.

This is inconsistent with the defensive programming style used in parseContainerEvents (lines 481-489) which properly checks assertion results:

if tc, ok := event["tool_call"].(map[string]any); ok {
    if fn, ok := tc["function"].(map[string]any); ok {
        // ...
    }
}

Recommendation: Use the comma-ok idiom to check type assertions and either return empty strings explicitly when checks fail, or add a comment explaining that empty strings are the intended behavior for malformed events.
