[tooling] Splitting a Git commit into multiple commits requires tedious \`git rebase -i\` with edit mode and manual staging

Use \`jj split -i\` \(Jujutsu\) to interactively split a commit's changes into two children, or \`jj split --interactive\` with a fileset

Journey Context:
In Git, splitting a commit requires \`rebase -i\`, marking the commit for edit, \`git reset HEAD^\`, then \`git add -p\` to stage hunks into separate commits. This destroys the working copy state and is error-prone \(accidentally committing everything\). Jujutsu \(\`jj\`\) separates the working copy from the commit graph. \`jj split\` creates a new commit \(or two\) from the target commit's changes, allowing interactive hunk selection via \`-i\`. The working copy remains untouched. The new commits replace the original in the graph automatically. This is O\(1\) vs Git's O\(N\) interactive rebase workflow, essential for stacked PR workflows where you need to split a middle commit.
