[NVBUG-6448152][test] TEST ONLY; DO NOT REVIEW historical source with current runtime

[chienchunhung]

Purpose

TEST ONLY. This diagnostic isolates the runtime/toolchain contribution to the PP4 context-side throughput change by retaining the previously fast historical source tree and changing only its five CI image assignments to the exact image set used by the current-source comparison.

Factor isolation

• Historical source parent: 5e2498b46a71, tree 68e92a26956da25a659860082da887567b9d36c3.
• The five historical image assignments from build 202606051544-14972 are replaced with the exact five assignments from current-source base a2fca7808c94, build 202607151440-16194.
• Product code, benchmark YAML, selector, workload, coordinator behavior, traffic, admission, and timeout settings are unchanged.

This is a one-factor crossover: historical source plus current runtime/toolchain. It is not intended for review or merge.

Validation

• The committed diff is exactly one file and five line substitutions.
• The resulting image-tag file is byte-identical to the current-source comparison's image-tag file.
• Shell parsing and all five required key/value checks passed.
• The image-renaming utility parsed all five entries in dry-run mode.
• Repository pre-commit and DCO checks passed.

Targeted validation is limited to the exact GB300 PP4 disaggregated performance-sanity workload. Throughput from this diagnostic will be interpreted only if every submitted request succeeds and the official metric is valid.
