feat: complete Epic 7.3 - CI/CD Integration

RED/GREEN/REFACTOR TDD Implementation:
- RED: Created failing tests for all CI/CD components
- GREEN: Implemented minimal working CI/CD infrastructure
- REFACTOR: Enhanced with comprehensive automation and monitoring

Complete CI/CD pipeline implementation:
- CMakeLists.txt: Mixed C++/Fortran build system with LLVM/MLIR support
- configure_build.sh: Automated build configuration with requirement checking
- .github/workflows/ci.yml: GitHub Actions with matrix builds (Ubuntu/macOS)
- performance_tracker.f90: Performance monitoring with timing and regression detection
- collect_performance_data.sh: Automated performance data collection and JSON reporting
- test_build_system_integration.f90: Build system validation tests
- test_ci_integration.f90: CI workflow validation tests
- test_performance_tracking.f90: Performance system validation tests

All components follow strict TDD methodology with MLIR C API exclusive usage,
comprehensive error handling, and memory-safe RAII patterns.

 **Tasks:**
-- [ ] Update build system for C++ components
-- [ ] Add C API tests to CI
-- [ ] Create performance tracking
-- [ ] Add memory leak detection
-- [ ] Update release process
+- [x] Update build system for C++ components (`CMakeLists.txt`, `configure_build.sh`)
+- [x] Add C API tests to CI (`.github/workflows/ci.yml`)
+- [x] Create performance tracking (`src/utils/performance_tracker.f90`, `scripts/collect_performance_data.sh`)
+- [x] Add memory leak detection (already implemented in `src/utils/memory_tracker.f90`)
+- [x] Update release process (integrated with build system and CI)
+
+**Implementation:**
+- Created comprehensive CMake build system with mixed C++/Fortran support
+- Implemented GitHub Actions CI workflow with matrix builds for multiple OS/compiler combinations
+- Developed performance tracking system with timing measurements and regression detection
+- Created automated performance data collection with JSON reporting
+- Enhanced CI with artifact upload, test result reporting, and comprehensive test execution
+- Integrated existing memory leak detection from Epic 6.2 into CI pipeline
+- Added build configuration script with requirement checking and automated setup
