fix(ci): artifacts move to stock upload-artifact@v7 / download-artifact@v8

android.yml's debug upload and release.yml's minstrel-apk pair went
through the bvandeusen fork mirrors, with comments saying stock actions
refuse this hostname, that the pair had to be matched on the bundled
@actions/artifact major, and that download v7 was off-limits for node24.
None of that holds on gitea/runner 3.x: the runner edits the GHES refusal
out of the action bundles, every download major v4-v8 reads every upload
major v4-v7 (Scribe spike #3843, CI-runner run 6312), and every CI image
carries Node 24. The mirror pair itself was last verified at tag run 6286.

Same artifact names, paths and if-no-files-found. ci-requirements.md
drops the pairing table and keeps what is still true: @v3 is invisible.

Scribe snippet #2271, milestone 395.
