[tooling] Manually checking out commits to find which commit introduced a regression is slow and error-prone

Use \`git bisect start\`, \`git bisect bad \`, \`git bisect good \`, then \`git bisect run

Journey Context:
Agents often manually binary search through history with \`git checkout\` and testing, which is non-repeatable and slow. \`git bisect run\` automates the binary search: you provide a script that tests the current HEAD \(e.g., \`grep -q 'bug' output.txt\`\). Git automatically checks out the midpoint, runs the script, and adjusts the search range based on the exit code. Exit 125 is crucial for 'skip' \(e.g., the commit doesn't compile\), telling bisect to ignore that commit and try another. This turns an O\(log n\) manual process into a fully automated, unattended operation.
