docs(pre-push-review): include uncommitted changes in diff scope

Switch the diff range from $BASE..HEAD to $BASE so the review covers
working-tree changes (committed + staged + unstaged), letting the skill
run usefully on in-progress work without requiring a commit first.

 If the user names a different base (e.g. `main`, a stacked branch), use that instead.
