Report #6818

[tooling] A bug was introduced somewhere in the last 100 commits and manually checking each commit to find the regression is time-consuming

Use \`git bisect run

Journey Context:
Manual binary search \(git checkout old-commit, test, decide, repeat\) is error-prone and slow. git bisect automates the binary search algorithm, but \`git bisect run\` fully automates the testing with a script. The script must return exit code 0 for 'good' \(no bug\) and 1-127 \(except 125\) for 'bad' \(bug present\); exit 125 means 'skip this commit' \(e.g., doesn't compile\). This allows overnight or CI-based bisection across thousands of commits. Unlike simply blaming a file, bisect finds the exact commit introducing the regression, crucial for understanding the context of the bug. The script can be as simple as \`\! grep -q BUG file.txt\` or as complex as running a full test suite. Essential for large codebases where linear search is impossible.
