Create HandTracker.jsx component that subscribes to /saltybot/hands (HandLandmarks msg with 21 landmarks per hand) and /saltybot/hand_gesture (String). Render hand skeleton overlay on a canvas — draw 21 landmark dots connected by bones (MediaPipe hand connections). Show classified gesture label (Point, Fist, Open, etc.) with confidence. Display handedness (L/R). Support up to 2 hands simultaneously. Add to a new HANDS tab in the SOCIAL tab group.
