Add GitHub Actions CI/CD pipeline and test framework

- Add .github/workflows/build-test.yml for automated testing
- Add tests/ directory with TypeScript test runner
- Add docs/CICD.md documentation
- Remove .gitlab-ci.yml (migrated to GitHub Actions)
- Update .gitignore for test artifacts

+criteria: |
+  Basic inference should work on Tesla K80.
+
+  Expected:
+  - Model responds to the math question
+  - Response should indicate "4" (accept variations: "4", "four", "The answer is 4", etc.)
+  - GPU memory should be allocated during inference
+  - No CUDA errors in output
+
+  This is AI-generated output - accept reasonable variations.
+  Focus on the model producing a coherent response.
