ci: collect native APK and screenshot evidence on Gitea

Bootstrap checksum-pinned ARM64 Node before Mac checkout, upload a dedicated installable native debug APK, collect AGP test output before UTP uninstall and reject stale/missing screenshots. Add five screenshot-output regressions and enforce native shipping-source invariants. Workflow lint, 10 runner and 8 JUnit verifier regressions pass; remote execution is not yet verified.
