fix: resolve workflow_run artifact access issue in release pipeline

- Replace actions/download-artifact@v4 with GitHub API calls to access artifacts from triggering workflow
- Add proper permissions (contents: read, actions: read) to prepare-assets job
- Handle both workflow_run and workflow_dispatch trigger scenarios
- Fix the root cause: workflow_run events cannot access artifacts from triggering workflows using standard download-artifact action

Fixes the 'Prepare release assets' step failure by implementing cross-workflow artifact access through GitHub API.
