fix: rewrite publish workflow using official actions/download-artifact@v4

Replace third-party dawidd6/action-download-artifact and
fountainhead/action-wait-for-check with:
- actions/github-script@v7 for polling workflow completion
- actions/download-artifact@v4 with run-id + merge-multiple

This fixes the subdirectory extraction issue that caused previous
publish attempts to find 0 wheels.
