feat(ci): enable auto-build for execution-traceability and preview/* branches

- Add execution-traceability and preview/** branches to workflow triggers
- Implement dynamic image tagging based on branch name
- Update concurrency group to use github.ref for branch isolation
- Add branch-specific build summaries with deployment instructions
