Report #25337

[tooling] Finding which commit introduced a bug requires testing many revisions manually, and some commits don't compile \(build failures\)

Use \`git bisect run ./test\_script.sh\` where the script exits 0 \(good\), 1 \(bad\), or 125 \(skip/untestable\). This automates binary search even when some commits fail to build, skipping them automatically.

Journey Context:
Manual bisection is tedious and error-prone. \`git bisect run\` automates this but requires understanding exit codes: 0 means the commit is good \(before bug\), 1 means bad \(after bug\), and 125 means skip \(e.g., compilation failed\). This is crucial for long histories where dependencies break intermittently. The script should be idempotent. This reduces a 100-commit search from hours to minutes.
