fix PR experiment additional arg parsing conflict

[wenta0g]

This PR fix the problem when issuing /gcbrun command with additional args -- additional_args. The additional_args may flow to web.py or run_all_experiment.py, causing web.py to fail when the args are exclusively to run_all_experiment.py

/gcbrun exp -n wentao -m vertex_ai_gemini-2-5-pro-chat -b quick-test -ns 1 -- -csv -ag

Hi @DonggeLiu, I checked the additional arg parsing conflict we discussed before. I am proposing to add an additional argument splitter in docker_run.py to parse and extract flags exclusive to web.py (e.g., -csv, -gs). Only the rest of the additional args will be piped to run_all_experiment.py

My example run added two additional args: -- -csv -ag, both are parsed as expected.
-csv to export a csv file in results dir, which is a web.py option, exported here: https://storage.cloud.google.com/oss-fuzz-gcb-experiment-run-logs/Result-reports/ofg-pr/2026-01-19-1217-wentao-quick-test/crashes.csv;
and -ag activated agent mode, evident from any of the logs: https://llm-exp.oss-fuzz.com/Result-reports/ofg-pr/2026-01-19-1217-wentao-quick-test/sample/output-astc-encoder-_z10encode_ise12quant_methodjpkhphj/01.html

Thanks @wenta0g!
It appears report generation failed again due to a bug in parse_training_data.py.
Would you mind commenting out these lines to unblock report generation at your convenience?

Feel free to do this in this PR or a new PR. I don' think the bug relates to this PR.

Thanks, Dongge! I removed the quoted lines under this PR.

Thanks, Dongge! I removed the quoted lines under this PR.

Thanks! Shall we run another experiment at your convenience to test report generation?

Hi @DonggeLiu, the public-facing report looks good to me. Let me know if there's any GKE issue that I'm not aware of.

Nope, this should be good to merge.

BTW, this is the correct report URL: https://llm-exp.oss-fuzz.com/Result-reports/ofg-pr/2026-01-20-1217-wentao-quick-test/index.html

There is a known date mismatch issue (2026-01-20 vs 2026-01-21-1217) in some github action comments due to timezone.

You can find the correct URLs at:
