- Add TestZoneBoundariesAtCorrectCoordinates to verify zone boundaries appear at correct pixel coordinates
- Add TestZoneBoundaryEdges to verify zone edge detection
- Enhance TestPixelColors with accurate background color verification (#1a1a2e)
- Fix person color detection by sampling multiple pixels to find red fill
- Tests verify 300x300 PNG dimensions, correct zone boundary coordinates, and accurate colors
- All renderer tests pass

Implements a 300x300 PNG floor-plan renderer using github.com/fogleman/gg:
- Room outlines (white rectangles on dark background)
- Zone fills (semi-transparent colored at 20% opacity)
- Zone labels (white text at centroid)
- Node positions (white dots)
- Person blobs (colored circles, diameter 10-20px based on confidence)
- Name labels above blobs
- Portal planes (thin purple lines #a855f7)
- Event highlight zone (brighter fill with white border)
Includes unit tests that verify pixel colors at known positions and
benchmark for performance validation (target: <200ms).
