feat: Major update with validators, skills, dashboard, and docs reorganization

- Add validation framework (config, model, results, study validators)
- Add Claude Code skills (create-study, run-optimization, generate-report,
  troubleshoot, analyze-model)
- Add Atomizer Dashboard (React frontend + FastAPI backend)
- Reorganize docs into structured directories (00-09)
- Add neural surrogate modules and training infrastructure
- Add multi-objective optimization support

+## Executive Summary
+The optimization study successfully converged after 45 trials. The best design achieved a mass reduction of 15% while maintaining all constraints.
+
+## Key Findings
+- **Best Objective Value**: 115.185 Hz
+- **Critical Parameter**: Plate Thickness (sensitivity: 0.85)
+- **Constraint Margins**: All safety factors > 1.2
+
+## Recommendations
+Based on the results, we recommend proceeding with the design from Trial #45. Further refinement could be achieved by narrowing the bounds for 'thickness'.
