ruv ebe217569b feat(examples): real live WiFi-CSI through-wall sensing demo ...

Self-contained Three.js r128 demo at examples/through-wall/ that renders
ONLY genuine data streamed from the running sensing-server over
ws://localhost:8765/ws/sensing. No simulation, no fabricated frames, no
fake skeleton.

Renders, driven by real /ws/sensing frames:
- 20x20 signal_field floor heatmap (real values)
- coarse RF-localization puck from persons[0].position (labeled coarse,
  NOT pose; peak signal_field cell as fallback)
- live motion/breathing/variance/rssi bars + motion sparkline
- presence/confidence/estimated_persons/active-node/tick/Hz meters
- 3D room with wall + doorway dividing office (node 9) / hallway (node 13)
- honest mutually-exclusive banner: LIVE (source=esp32) / SIMULATED /
  NO SERVER, showing the real source verbatim
- optional webcam tile (ground-truth-when-visible, separate from CSI)

Reuses scene/lights/bloom/CSS + webcam path from
examples/three.js/demos/05-skinned-realtime.html, the floor-heatmap idea
from ui/observatory/js/, and the threaded no-cache server from
examples/three.js/server/serve-demo.py (serve.py on :8080).

Verified against the live server: real frame source=esp32, nodes [9,13],
400 signal_field values, persons[0].position present. Python proof PASS.
