Report #15100

[tooling] Finding regression commit with git bisect requires manual good/bad marking

Use \`git bisect run ./test.sh\` where the script exits 0 for good, 1-127 for bad, and 125 for skip; git automates the binary search loop and reports the exact first bad commit.

Journey Context:
Manual bisecting forces you to run a test, mark state, and repeat log2\(n\) times, which is tedious and error-prone. \`bisect run\` automates the loop, handles 'skip' automatically if the script exits 125, and stops exactly at the regression. The tradeoff is you must write a deterministic, automated test script that can distinguish good from bad states, but this enforces reproducibility.
