Add FFT-based breathing detection with long-dwell presence tracking:
- FFTBreathingDetector: Rolling 30-second buffer, Hann window, FFT analysis
to detect periodic breathing signals in 0.2-1.0 Hz band
- DwellTracker: State machine with CLEAR → MOTION_DETECTED →
POSSIBLY_PRESENT → STATIONARY_DETECTED transitions
- Health gating: Detection disabled when link health < 0.7
- Dashboard: Slow-pulsing blue dot for stationary detection with BPM tooltip
- Timeline: Event logging on transition to STATIONARY_DETECTED
Physics: CSI phase oscillates at 2x breathing rate due to round-trip
path length change. 15 BPM breathing → 0.5 Hz CSI phase oscillation.

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.

Web Serial-based wizard that takes a non-technical user from unboxed
ESP32-S3 to streaming CSI in under 5 minutes. 8-step state machine:
browser check → connect → flash firmware (esp-web-tools) → provision
WiFi → detect node → guided calibration → placement guidance → complete.
Includes sessionStorage persistence for resumability across page refreshes,
live CSI waveform during calibration, human-friendly error messages for
all failure modes, and comprehensive Jest test coverage (34 tests).

Add 500ms periodic presence_update broadcast from the dashboard hub with
per-link motion state (is_motion, delta_rms, confidence). Surface this in
a new Presence panel on the dashboard with coloured dot indicators
(green=clear, amber=motion, red=high-confidence) and deltaRMS values.
Includes a rolling 10s Canvas 2D line chart of deltaRMS with a threshold
line at 0.02 for the selected link.

Implements plan item 17 — full Three.js Phase 3 visualization layer:
- Room bounds: floor, ceiling, semi-transparent walls and wireframe edges
built from registry_state room config (width/depth/height/origin)
- Floor plan texture: upload any image via status-bar button; mapped to
ground plane via THREE.TextureLoader
- Humanoid figures: SkinnedMesh + AnimationMixer with 13-bone skeleton;
four AnimationClip postures (standing, walking, seated, lying); smooth
0.35 s crossfade transitions; walking speed scales animation timeScale;
figures orient in direction of travel
- Vertical pillar anchors: line from floor to ceiling at each blob position
- Footprint trails: floor-level Line geometry following blob.trail history
- Node meshes: OctahedronGeometry at registry node 3-D positions; link
lines redrawn whenever link_active/inactive events arrive
- View presets: 3D perspective, top-down orthographic, first-person follow
(lerps camera to track first active blob)
- WebSocket: handles registry_state, loc_update, link_inactive message types
newly routed through handleJSONMessage; existing CSI/motion pipeline intact

- Dashboard hub broadcasts motion state changes immediately on transition
(idle↔motion) via BroadcastMotionState; periodic state snapshots include
motion_states for new client init
- Per-link presence badge (green CLEAR / red MOTION) rendered in link list
alongside global presence indicator in status bar
- Amplitude mean time-series chart (60 s rolling window) for selected link,
line segments colored by motion state at each sample
- Fix: links created from JSON link_active/state events now initialize
ampHistory and lastAmpSample so time-series accumulates from first frame

- Dashboard presence indicator: per-link MOTION/CLEAR badges with global
status bar indicator, motion_state WebSocket messages, amplitude chart
- CSI recording buffer: disk-backed circular buffer (replay/store.go) with
magic-tagged binary format, wrap/eviction, 360 MB default (~48 h at 20 Hz)
- Adaptive sensing rate: RateController ramps nodes to 20 Hz on motion,
drops to 2 Hz after 10 s idle; wires to SendConfigToMAC over WebSocket
- Fix: alias internal/signal as sigproc to avoid conflict with os/signal
- Fix: add GetAllMotionStates() to MockIngestionState in dashboard tests
All tests pass (signal, ingestion, replay, dashboard).
