Implements comprehensive pre-deployment simulator for WiFi CSI-based
positioning that allows users to predict detection quality before
purchasing hardware.
Components:
- Virtual space definition with rooms, walls, and material properties
- Virtual nodes with configurable roles (TX/RX/TX_RX/PASSIVE/IDLE)
- Synthetic walkers (random walk, path-following, node-to-node)
- GDOP overlay for coverage quality visualization
- Signal propagation model with path loss and wall attenuation
- Fresnel zone accumulation for blob detection
- REST API endpoints for simulator control
- Dashboard integration with space/node/walker management
- Coverage optimization recommendations
The simulator produces realistic synthetic CSI data matching
real-world conditions by using the same propagation models and
localization algorithms as the live system.

Adds TransformControls for dragging nodes in the 3D scene, a room dimension
editor (width/depth/height), a GDOP (Geometric Dilution of Precision) coverage
overlay on the ground plane that updates in real-time during node drag, virtual
node support for planning optimal placement before hardware purchase, and REST
API integration to persist positions and room config to the mothership.
Backend adds PUT /api/nodes/{mac}/position, POST /api/nodes/virtual,
DELETE /api/nodes/{mac}, PUT /api/room endpoints. Also wires OTA status
handler and improves firmware manifest to use actual latest binary filename.
