ci: add upstream sync workflows and optimize Docker CI builds

- Add auto-upstream-sync workflow with dedup protection for conflict issues
- Add upstream-sync build + smoke test workflow
- Add smoke-test script and test files
- Add upstream sync issue template and documentation
- Fix: use --allow-unrelated-histories for merge command
- Fix: check for existing open merge-conflict issues before creating duplicates
