NeoPixel status patterns + smooth transitions

NeoPixel status patterns + smooth transitions
sl-jetson added 2 commits 2026-03-05 08:55:53 -05:00 
NeoPixel status indicators with animated patterns:
- Breathing blue (idle state)
- Green pulse (follow mode)
- Red flash (error state)
- Rainbow animation (celebrate)
- Amber pulse (low battery <20%)
- White chase (search mode)

Features:
- Smooth transitions between states
- Configurable LED count (default 30) and GPIO pin (default GPIO18)
- Auto-dim brightness control
- Subscribes to battery, balance, social, emotion, health topics
- Publishes LED state JSON to /saltybot/led_state
- 30Hz update frequency with multiple animation patterns

Configuration:
- YAML-based hardware and pattern settings
- Per-pattern speed and color customization
- State priority system for concurrent status indicators
