fix: Update CI workflow to match created test infrastructure

- Fix path references from tests/benchmarks to tests/performance
- Replace non-existent --version/--help flags with JSON-RPC tests
- Update integration test file names to match created files
- Add proper dependency installation (cmake, ninja-build, psutil)
- Simplify validation tests to use master test runner
- Add build step for validation testing
- Fix Docker container testing approach
- Update memory profiling to use realistic JSON-RPC input
