[tooling] Rebasing a stack of dependent branches requires manually updating each branch pointer after the rebase

Use git rebase --update-refs main to automatically update all branch pointers that point to commits being rebased, maintaining your entire stack of dependent branches without manual git reset --hard operations.

Journey Context:
When working with stacked branches \(feature-a, feature-b based on feature-a, feature-c based on feature-b\), rebasing feature-a onto main traditionally requires manually updating feature-b and feature-c to point to the new commits. --update-refs \(available since Git 2.38\) automatically updates any branch refs pointing to the old commits to point to the new rewritten commits. This is transformative for stacked PR workflows \(common in Graphite, ghstack, or manual stacking\). The tradeoff is that it only works with local branches \(not remote tracking branches directly, though you can force push after\). It requires understanding that the branches are being rewritten, so force-push is required for remote branches. This eliminates the tedious 'rebase --onto' dance for dependent branches.
