Code Review: Update actions/setup-java action to v5

Summary

This is a Renovate-generated PR that bumps actions/setup-java from v4 to v5 (a major version upgrade) across two GitHub Actions workflow files (build.yml and deploy-apk.yml). All CI checks passed and the change has been merged. The diff is minimal (2 lines changed across 2 files), but as a major version bump, it warrants a quick compatibility check.

Blocking Issues

None. The CI build jobs completed successfully, confirming the v5 action works with the current workflow configuration.

Non-blocking Suggestions

1. distribution: 'adopt' is deprecated — consider switching to temurin

• Files: .github/workflows/build.yml (line 15), .github/workflows/deploy-apk.yml (line 19)
• Current: distribution: 'adopt'
• Issue: AdoptOpenJDK transitioned to Eclipse Adoptium (Temurin) back in 2021. The adopt distribution identifier has been deprecated in actions/setup-java since v3 in favor of temurin. While it still works today (CI passes), it may be removed in a future version and points to stale/unmaintained binaries.
• Suggested fix:

  distribution: 'temurin'

  This would align with current best practices and ensure forward compatibility.

2. Renovate PR description lacks v5 release notes

The PR body only links to a compare view (v4...v5) with no actual changelog or breaking change details. For a major version bump, it would be valuable to review the actions/setup-java releases page to understand what changed and whether any new features or deprecations apply.

Questions / Clarifications

None — the change is straightforward and CI validates it works as-is.
