Dragonframe's development branch rewrites its graphics engine and adds robotic-arm motion control

Dragonframe's public development-branch changelog shows the software's core rendering engine changing under the hood -- "Replace OpenGL code with QRhi (Metal/D3D11/Vulkan)" -- alongside continued camera-list growth (Canon EOS C50 and R6 V, Panasonic S5D, Fujifilm autofocus) and new DMX fixture definitions for working lighting manufacturers including ARRI, Nanlite and Nanlux. The bigger change is in Arc, Dragonframe's motion-control workspace: new entries add direct support for six-axis Universal Robots arms over UR's RTDE network protocol, with Dragonframe labelling the capability "go-motion with robotic arms" -- driving an industrial cobot through a keyframed move rather than only a simple stepper-motor rig. The changelog reads as a working feature under active debugging (fixes for RTDE connection hangs, jog-on-line speed/direction, and servo jitter), not a marketing announcement; no shipped production is yet named as using it.
