Major changes: - Dashboard: WebSocket-based chat with session management - Dashboard: New chat components (ChatPane, ChatInput, ModeToggle) - Dashboard: Enhanced UI with parallel coordinates chart - MCP Server: New atomizer-tools server for Claude integration - Extractors: Enhanced Zernike OPD extractor - Reports: Improved report generator New studies (configs and scripts only): - M1 Mirror: Cost reduction campaign studies - Simple Beam, Simple Bracket, UAV Arm studies Note: Large iteration data (2_iterations/, best_design_archive/) excluded via .gitignore - kept on local Gitea only.
