Report #103004

[tooling] A regression appeared between two known commits and manual inspection is too slow

Automate the hunt with \`git bisect run ./test.sh\`: \`git bisect start\`, \`git bisect bad HEAD\`, \`git bisect good v1.2.3\`, then \`git bisect run ./repro.sh\`. The script must exit 0 for good and 1-127 \(except 125\) for bad; 125 skips the commit.

Journey Context:
Binary search cuts thousands of commits to ~log2\(N\) tests, but humans repeatedly building and judging commits is error-prone and slow. \`git bisect run\` drives the search automatically using any script that returns the right exit codes. It is especially powerful paired with a minimal reproducer or a failing test. Skip status 125 tells bisect to ignore unbuildable commits instead of aborting.
