[tooling] Manual git bisect is slow and error-prone for finding regressions

Use \`git bisect run

Journey Context:
Manual bisecting requires repeatedly checking out commits, building/testing, then typing \`git bisect good\` or \`git bisect bad\`. This is tedious for long histories and impossible if the test takes time—agents often skip bisecting entirely and guess at the cause. \`git bisect run\` automates the binary search: it requires only a test script \(which can be as simple as \`make test\` or a shell function checking output\). Git handles the binary search logic, skipping unmergeable commits automatically. This is the only scalable method for finding regressions in large repositories; it reduces a 20-step manual process to a single command and guarantees the correct commit is identified without human error in marking good/bad boundaries.
