fix: only rename top-level template dir in Windows zip extraction

The zip extraction was replacing ALL {{cookiecutter.*}} directory names
with {{cookiecutter.project_name}}, including nested ones like
{{cookiecutter.project_slug}}. This caused src/replace_me/ to become
src/replace-me/ on Windows, breaking Python imports. Only rename the
top-level template dir (which has NTFS-illegal pipe and quote chars).
