feat(evals): add overall pass rate row to eval nightly summary table

[gundermanc]

Summary

Adds a row below the header in the markdown table showing the overall pass rate for each historical and current run in the nightly evals script.

Makes it easier to spot regressions across runs, at a glance.

Details

Improves the readability of the aggregate_evals.js script output by quickly surfacing the top-level pass/fail percentage of the current and past test runs.

Related Issues

None.

How to Validate

1. Provide an artifacts directory to the script or run it locally if you have gh cli access to recent runs.
2. Observe the summary table includes a new row | **Overall Pass Rate** | ... |.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the readability of the nightly evaluation summary by introducing an 'Overall Pass Rate' row in the generated markdown table. This addition provides an immediate visual cue for the pass/fail percentage across different test runs, making it significantly easier to identify performance regressions at a glance without delving into individual test results.

Highlights

• Overall Pass Rate Row: Added a new row to the nightly evaluation summary markdown table, displaying the overall pass rate for each historical and current run.
• Pass Rate Calculation Refactoring: Introduced a new helper function, getPassRate, to centralize and reuse the logic for calculating pass rates, improving code readability and maintainability.

Changelog

• scripts/aggregate_evals.js
  • Refactored pass rate calculation into a dedicated getPassRate function.
  • Implemented logic to generate and display a new 'Overall Pass Rate' row in the markdown table.

Code Review

This pull request adds an 'Overall Pass Rate' row to the markdown table in the nightly evals summary. This is a useful enhancement for quickly assessing performance trends. The implementation refactors the pass rate calculation into a reusable getPassRate function, which is then used to populate the new row for both historical and current runs. The code is clear and effectively implements the desired feature. I found no issues with the changes.
