sl-webui d10c385bdc feat: Add Issue #429 - Emotion engine with context-aware face expression selection

- ROS2 node subscribing to orchestrator state, battery, balance, person tracker, voice commands, health
- State-to-emotion mapping: navigation → excited, social → happy/curious, low battery → concerned, etc.
- Smooth emotion transitions (0.3–1.2s) with confidence tracking
- Idle behaviors: blink (~3s), look-around (~8s), breathing (sine wave)
- Social memory: familiarity-based warmth modifier (0.3–1.0) for known people
- Personality-aware responses: extroversion, playfulness, responsiveness, anxiety (0.0–1.0 configurable)
- Publishes /saltybot/emotion_state (JSON): emotion, intensity, confidence, expression name, context, idle_flags
- Configurable via emotion_engine.yaml: personality traits, battery thresholds, update rate
- Launch file: emotion_engine.launch.py

Jetson Nano — AI/SLAM Platform Setup

Self-balancing robot: Jetson Nano dev environment for ROS2 Humble + SLAM stack.

Stack

Component	Version / Part
Platform	Jetson Nano 4GB
JetPack	4.6 (L4T R32.6.1, CUDA 10.2)
ROS2	Humble Hawksbill
DDS	CycloneDDS
SLAM	slam_toolbox
Nav	Nav2
Depth camera	Intel RealSense D435i
LiDAR	RPLIDAR A1M8
MCU bridge	STM32F722 (USB CDC @ 921600)

Quick Start

# 1. Host setup (once, on fresh JetPack 4.6)
sudo bash scripts/setup-jetson.sh

# 2. Build Docker image
bash scripts/build-and-run.sh build

# 3. Start full stack
bash scripts/build-and-run.sh up

# 4. Open ROS2 shell
bash scripts/build-and-run.sh shell

Power Budget (Summary)

Scenario	Total
Idle	2.9W
Nominal (SLAM active)	~10.2W
Peak	15.4W

Target: 10W (MAXN nvpmodel). Use RPLIDAR standby + 640p D435i for compliance. See docs/power-budget.md for full analysis.
