v0.3.0 — 2D Editing

What's new in v0.3.0

2D Floorplan panel

A full top-down drafting view for drawing and editing building layouts:

• Draw walls with snap-to-grid at 0.5m increments
• Place doors and windows directly on walls
• Edit zone and slab polygons with vertex and midpoint drag handles
• Pan, zoom, marquee selection, multi-select (⌘/Ctrl+click)
• Wall endpoint dragging with junction miter recalculation
• Overlay reference images as tracing guides
• Dark/light theme support

Wall measurement labels

3D overlay labels that show wall lengths in the viewport. They follow the camera, respect your unit preference (metric/imperial), and account for wall miter geometry so measurements are accurate even at junctions.

Command palette rewrite

Rebuilt from scratch with a registry-based architecture:

• useCommandRegistry and usePaletteViewRegistry stores for extensibility
• Commands grouped by category (View, Edit, Navigate, Create)
• Visual keyboard shortcut tokens
• Navigable pages and full-screen modes

Wall footprint geometry

New getWallPlanFootprint() in core — generates miter-aware 2D polygons for walls, used by both the floorplan panel and measurement labels.

Other improvements

• Node action menu — quick operations on selected scene nodes
• Selection manager — improved multi-select with ⌘/Ctrl+click toggle
• Camera focus — camera-controls:focus event centers the camera on a node's bounding box
• Error boundary — broken item models show a fallback instead of crashing the viewer
• Ground occluder fix — upper floor shadows no longer bleed through lower levels
• Undo history — pauses correctly during batch operations (space detection, AI actions)
• Dirty marking — siblings and parents marked dirty on deletion so wall miters recalculate
