My only comment would be to check if AGENTS.md file in this example needs to be updated in anyway in regards to this new feature

Purpose
Adds a dedicated uvc_controls C++ layer and wires it into cpp/uvc/src/uvc_example.cpp so host UVC requests for AE mode, exposure time, brightness, gain, and an extension control are translated into DepthAI CameraControl commands.
Specification
The change adds a new uvc_controls module and wires it into uvc_example to register UVC controls and forward them to DepthAI CameraControl. It also updates uvc-start.sh to advertise camera terminal, processing unit, and optional extension-unit controls in configfs.
Dependencies & Potential Impact
Needs latest depthai and OS 1.33.
Deployment Plan
None
Testing & Validation
Tested on Windows with https://github.com/luxonis/uvc-demo-app
