Note

High Risk
Large new surface: external DXF/Madori/Vision/ComfyUI dependencies, scene writes, and optional catalog source mutation in non-dev when env flags are enabled.

Overview
Adds an end-to-end DXF floor-plan import flow: canvas preview and validation UI, file-based job queue under PASCAL_DATA_DIR, parallel geometry + vision-analyze (Anthropic) merge, scene persistence via buildAndSaveScene, and an alternate 3dMadori path (/api/dxf-jobs/.../madori). Core importer modules and job-store are documented in AGENTS.md and the new dxf-import agent skill.

The editor gains ImportDxfTool (home modal + /import-dxf), sidebar tabs for AI assistant, catalog Add, panorama/walkthrough, MeasureNavi theming (Inter/JetBrains), and /api/ai proxy that buffers long chat responses. Catalog POST/PATCH/DELETE and dev overlay APIs can write source/public/items when dev or PASCAL_ALLOW_CATALOG_SOURCE_WRITE is set.

Also ships image-to-3D (/pic-to-3d + ComfyUI API routes), expanded SETUP/README (editor 3002, AI 8788, .NET proxy 8000), ai-ci for pascal-ai-mcp, MCP config samples, and runbooks (WINDOWS_DEPLOY_RUNBOOK, CATALOG_ITEMS, SAVE_BUILD_JSON).
