Create a ROS2 node that subscribes to /saltybot/detected_faces (face bounding boxes + landmarks from existing face detection). Extract facial landmark geometry (mouth openness, eyebrow raise, eye squint ratios) and classify into emotions: neutral, happy, surprised, angry, sad. Use simple geometric rules (not ML). Publish /saltybot/face_emotions (custom FaceEmotion msg with face_id, emotion label, confidence). Include tests.
