Update result summarizer to utilize id_json_file for public ids

[arav-agarwal2]

Part of resolving mlcommons/training#854

Adds a optional argument to supply id_json_path, a list of hashed ids which serves as a map from each result record to the actual repo ID.

Summaries will include both a hash column and an id column to ensure that each run is given a unique id and previous ids are respected.

@arav-agarwal2 can you please rebase?

[arav-agarwal2]

I believe I've done just that - let me know if I'm missing something

WG discussed on 3/5/26 and planning to keep this open another week before finalizing.

I've made a pass and have resolved your issues to the best of my ability.

One thing I wanted to point out is that the ids currently are stored like "tinybox_green_privateid.json", where "tinybox_green" is the name for the system provided by the submitter. I understand this may be an issue ( as this could be changed by the submitter ), so if there's a better way to handle storage please let me know.

Thanks, Arav. It looks great!
Why not set the filename to be consistent like privateid.json so that in the future, it'll be easy to find all the privateid.json files and probably update them with simple bash commands in case we want to do that?

[arav-agarwal2]

I've added a few lines to the README as suggested.

We should be A-OK for the merge.

LGTM, thanks for addressing all the concerns!
