Add advanced computer vision module for robotics AGI

[Copilot]

Adds a comprehensive vision/ Python package providing modular, lazily-loaded computer vision capabilities (detection, segmentation, depth, tracking, pose, VLM, motion, scene understanding) for a robotics AGI system.

Module structure

• detection/ — YOLODetector (ultralytics), DETRDetector (HF transformers), PersonDetector, HandDetector (MediaPipe), GraspDetector; shared BaseDetector with NMS
• segmentation/ — SemanticSegmentor (DeepLabV3+), InstanceSegmentor (Mask R-CNN), SAMSegmentor, PanopticSegmentor
• depth/ — MonocularDepthEstimator (MiDaS), DepthAnythingEstimator, StereoDepthEstimator, PointCloudGenerator
• tracking/ — MultiObjectTracker (Kalman filter), ByteTracker, DeepSORTTracker, ReIDModel
• pose/ — HumanPoseEstimator (17 keypoints, fall detection), ObjectPoseEstimator (6-DoF PnP), HandPoseEstimator (gestures), Pose3DEstimator
• features/ — FeatureExtractor (ORB/SIFT/AKAZE/deep), FeatureMatcher, VisualOdometry
• scene/ — SceneAnalyzer, AffordanceDetector, SceneGraph, SpatialRelations
• vlm/ — CLIPInterface, VisualQA (BLIP-2), ImageCaptioner (BLIP), VisualGrounding (OWL-ViT)
• motion/ — OpticalFlow (Farneback/LK), MotionSegmentor, MotionPredictor
• preprocessing/ — ImageEnhancer, Denoiser, SuperResolution
• utils/ — visualization helpers, transforms, metrics (mAP/MOTA/PCK), camera projection utilities
• models/ — ModelLoader with registry + disk cache, SimpleCNN, UNet, DetectionHead

Unified pipeline

All modules are accessible via a single lazy-loading entry point:

from vision import VisionPipeline

vision = VisionPipeline(enable_detection=True, enable_depth=True, device="cuda")

results = vision.process_frame(image)
# results.objects, results.depth_map, results.scene_description, ...

cup = vision.find_object("red cup")   # CLIP-guided retrieval
vision.answer("Is the door open?")    # VQA

Supporting files

• vision/config/ — YAML configs for detection, segmentation, and depth defaults
• requirements.txt / setup.py — full dependency manifest
• tests/test_vision/ — 74 unit tests; heavy model paths mocked so the suite runs without GPU
• .gitignore — excludes __pycache__, model weights, build artifacts
