fix: use extended-length path prefix to bypass NTFS char restrictions

Python's zipfile.extractall() strips double-quote characters from
paths on Windows since NTFS rejects them. Use the \\?\ extended-length
path prefix when extracting, which bypasses NTFS filename validation
and allows the template directory with quotes to be created.
