CI: build and test WPF R1 on Windows

[keida]

Summary

• add a minimal Windows GitHub Actions workflow for WPF R1
• restore and build the product in Release configuration
• build and run the existing deterministic WPF test runner
• add matching CI status badges to the Chinese and English READMEs

Security and scope

• workflow permissions are limited to contents: read
• official Actions are pinned to immutable commit SHAs
• no secrets, deployment, packaging, artifact upload, real authentication, UI automation, or release operations
• wpf/** and native/** product source is unchanged

Local verification

• Release product build: PASS, 0 warnings, 0 errors
• deterministic test runner build: PASS, 0 warnings, 0 errors
• deterministic tests: PASS, 31 fixtures / 58 checks
• privacy and exact-file review: PASS

The GitHub-hosted Windows run is the independent CI validation for this change.
