ci: store build artifacts in Namespace workspace

Switch all upload-artifact/download-artifact steps from actions/*@v5 to
namespace-actions/*@v1 (drop-in compatible, same inputs) so build
artifacts (APK, libcore.aar, sidecars) land in the Namespace workspace
storage instead of GitHub. Upload and download are switched in lockstep
since the two storages are not cross-compatible.
