[tooling] Finding which commit introduced a regression requires manually checking out and testing many commits

Use \`git bisect start \` followed by \`git bisect run ./test-script.sh\` to automate binary search; git checks out commits and runs the script until it finds the culprit

Journey Context:
Manual bisecting involves checking out a commit, running tests, marking good/bad, and repeating—a tedious process prone to human error in the binary search logic. \`git bisect run\` automates this entirely: you provide a script that exits 0 for "good" and non-zero for "bad", and git handles the binary search algorithm, checkout management, and final identification of the first bad commit. This turns a 30-minute manual task into a 2-minute automated one. The requirement is a reliable automated test script, but this is standard for regression hunting in professional workflows.
