alpaka split job

[fbzli]

Depends on #71

[Copilot]

Pull request overview

Splits the Alpaka build+upload workflow into separate jobs and introduces consistent working-directory handling and artifact stashing/unstashing so upload can run using build outputs from a prior job.

Changes:

• Added working-directory input/defaults and updated artifact stash/unstash paths to support Gradle projects not located at repo root.
• Refactored Alpaka workflow into build (assemble + stash outputs) and upload (restore outputs + publish) jobs.
• Adjusted concurrency/job naming and artifact retention/compression settings.

• Same path concatenation issue here: downloading into ${{ inputs.working-directory }}${{ needs.build.outputs.app_module_path }}/... relies on inputs.working-directory ending with /. Prefer explicit path joining to accept both android and android/ inputs reliably.

• This download-artifact path has the same concatenation fragility as the upload step: it depends on inputs.working-directory ending with /. Prefer explicit path joining to avoid subtle path errors for callers.
