refactor: Major reorganization of optimization_engine module structure
BREAKING CHANGE: Module paths have been reorganized for better maintainability.
Backwards compatibility aliases with deprecation warnings are provided.
New Structure:
- core/ - Optimization runners (runner, intelligent_optimizer, etc.)
- processors/ - Data processing
- surrogates/ - Neural network surrogates
- nx/ - NX/Nastran integration (solver, updater, session_manager)
- study/ - Study management (creator, wizard, state, reset)
- reporting/ - Reports and analysis (visualizer, report_generator)
- config/ - Configuration management (manager, builder)
- utils/ - Utilities (logger, auto_doc, etc.)
- future/ - Research/experimental code
Migration:
- ~200 import changes across 125 files
- All __init__.py files use lazy loading to avoid circular imports
- Backwards compatibility layer supports old import paths with warnings
- All existing functionality preserved
To migrate existing code:
OLD: from optimization_engine.nx_solver import NXSolver
NEW: from optimization_engine.nx.solver import NXSolver
OLD: from optimization_engine.runner import OptimizationRunner
NEW: from optimization_engine.core.runner import OptimizationRunner
