docs: setup instructions match what a render contains

The post-generation message pointed at NEW_LIBRARY_CHECKLIST.md, which
7509b31 had moved out of template/, so no render contained it. README.md and
.claude/LIBRARY_CREATION.md told the reader to git rm scripts/setup_repo.py
and .claude/LIBRARY_CREATION.md from the new library, and neither file is in
a render. The checklist's manual publish route pushed a tag and created a
GitHub Release, and nothing listens to either.

The checklist is rendered again (copier update leaves it deleted once a
library deletes it). The delete instructions are gone, and what remains says
to run setup_repo.py from the template repository. The manual route is the
Publish workflow's dispatch from master, which is how every successful
manual publish in the org has been done.

Closes #15
