[tooling] Managing stacked Git branches manually creates tedious chain rebasing

Use \`git rebase --update-refs main\` when rebasing a stack of dependent branches; Git automatically updates all downstream branch pointers without manual \`git rebase\` for each layer.

Journey Context:
Developers working with stacked PRs \(feature-a → feature-b → feature-c\) traditionally must rebase each branch individually after main moves, or use \`git rebase --onto\` chains. \`--update-refs\` \(Git 2.38\+\) treats branches as pointers into the rebased history graph, atomically moving them. This avoids the 'forgot to rebase the middle branch' error that breaks PR chains. Unlike \`git rebase --interactive\` with exec hooks, this requires no manual sequencing.
