Subject: [PATCH] fix(ci): publish from single build leg to avoid wheel content
 conflicts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pure Python package produces py3-none-any wheel — identical filename
from all 9 matrix legs but non-identical content (timestamps, metadata
ordering). Use ubuntu-latest py3.11 artifacts only, matching smoke-test.
