Install the difftree CLI and/or add difftree PR diff-tree comments to a repository. Use when the user says "install difftree", "set up difftree", "add difftree to my repo", "add PR diff-tree comments", "set up difftree-action", or wants difftree running locally or in CI. Installs the difftree CLI (prebuilt binary, `cargo install difftree`, or from source) and scaffolds a `.github/workflows/pr-diff-tree.yml` that runs smorinlabs/difftree-action from this repo's canonical examples/pr-diff-tree.yml, then commits or opens a PR. This is the difftree-action repo's own setup skill; the difftree CLI repo ships a lightweight pointer to it.
