08bc23f6df feat: Phone video streaming bridge (Issue #585)
Phone side — phone/video_bridge.py:
- MJPEG streaming server for Android/Termux phone camera
- Dual camera backends: OpenCV VideoCapture (V4L2) with automatic
  fallback to termux-camera-photo for unmodified Android
- WebSocket server (ws://0.0.0.0:8765) — binary JPEG frames + JSON
  info/error control messages; supports multiple concurrent clients
- HTTP server (http://0.0.0.0:8766):
    /stream    — multipart/x-mixed-replace MJPEG
    /snapshot  — single JPEG
    /health    — JSON stats (frame count, dropped, resolution, fps)
- Thread-safe single-slot FrameBuffer; CaptureThread rate-limited with
  wall-clock accounting for capture latency
- Flags: --ws-port, --http-port, --width, --height, --fps, --quality,
  --device, --camera-id, --no-http, --debug

Jetson side — saltybot_phone/phone_camera_node.py:
- ROS2 node: receives JPEG frames, publishes:
    /saltybot/phone/camera            sensor_msgs/Image (bgr8)
    /saltybot/phone/camera/compressed sensor_msgs/CompressedImage
    /saltybot/phone/camera/info       std_msgs/String (stream metadata)
- WebSocket client (primary); HTTP MJPEG polling fallback on WS failure
- Auto-reconnect loop (default 3 s) for both transports
- Latency warning when frame age > latency_warn_ms (default 200 ms)
- 10 s diagnostics log: received/published counts + last frame age
- Registered as phone_camera_node console script in setup.py
- Added to phone_bringup.py launch with phone_host / phone_cam_enabled args

df49eec21f feat: Android/Termux OpenClaw node (Issue #420)
Add complete phone node infrastructure:

ROS2 Package (saltybot_phone):
- camera_node: /phone/camera/image_raw (320x240, 15 FPS)
- gps_node: /phone/gps (NavSatFix via termux-api)
- imu_node: /phone/imu (accelerometer data)
- openclaw_chat_node: Local LLM inference
  Subscribes /saltybot/speech_text
  Publishes /saltybot/chat_response
- ws_bridge: WebSocket bridge to Jetson Orin (:9090)

Phone Scripts:
- termux-bootstrap.sh: Complete Termux setup
- power-management.sh: Battery/thermal monitoring
- README.md: Setup documentation

Architecture:
- Termux on Android phone
- WiFi/USB tether to Jetson Orin
- ROS2 topic bridge for sensors
- Local LLM for on-device chat (Phi-2)
- Termux:Boot auto-start
- Power management for extended runtime
