testing: track the llama export times

[mroreo]

Summary:

Based on the initial test times the following times were logged for each of the model export times from the following run

Run IDs:

• 19151256445
• 19052918428
• 19052918424
• 19151256463

Summary

Fixes #10761

Test Plan:

A script is included in this PR to automatically summarize the model export times based on the run ids. As of right now it is a melted table, but this can easily be grouped by different types using pandas groupby if you want to run analyses by the different columns.

python scripts/check_model_export_times.py --github_token="YOUR_GITHUB_ACCESS_TOKEN" --run_id 19151256445 19052918428 19052918424 19151256463

Once the PR is merged, you can then run this by filter date to get all the model export times after a specific date

python scripts/check_model_export_times.py --github_token="YOUR_GITHUB_ACCESS_TOKEN" --created_time="2025-11-01"

@lucylq can you please help re-run the tests

[mroreo]

@lucylq can you help re-run this. I added more configurations and updated the times

[mroreo]

@lucylq could i get a review for this PR?

[mroreo]

@lucylq how can i get the tests to pass to get this PR merged? New PRs seem to be merging, and then breaking some tests that are unrelated with this PR

[lucylq]

Hi @mroreo sorry for the late response - could you rebase the PR? I will track it and try to merge it. If the test failures are unrelated, we can just click Squash and merge
