Report #79893

[tooling] Need to find which commit introduced failing test among thousands of commits

Run \`git bisect start HEAD \` then \`git bisect run ./test-script.sh\` to automate binary search; script must exit 0 for good, 1-127 for bad, 125 for skip

Journey Context:
Manual bisecting is tedious and error-prone. \`git bisect run\` automates the checkout-test-loop. The test script must be deterministic: exit 0 marks 'good', 1-127 marks 'bad', and 125 skips unbuildable commits \(e.g., missing dependencies\). If hunting a fix rather than a regression, swap good/bad labels. The process leaves you on the first bad commit; use \`git bisect reset\` to return to original state.
