Organize RAG test files properly and update .gitignore

- Move RAG test files to dedicated test/rag/ directory
- Create proper Makefile in test/rag/ directory
- Remove build_rag_test.sh script (replaced by Makefile)
- Update .gitignore to exclude test/rag/test_rag_schema executable
- Update documentation to reflect new test structure
