Deps: move panel detection libs to devDependencies

Move OpenCV, TensorFlow.js, and COCO-SSD from optionalDependencies
to devDependencies. These libraries are now bundled into the vendor
directory during build instead of being optional runtime dependencies.

Also upgrade @rollup/plugin-terser from 0.4.4 to 1.0.0 which
requires Node.js 20+ and includes updated dependencies.

- Move @techstark/opencv-js to devDependencies
- Move @tensorflow/tfjs to devDependencies
- Move @tensorflow-models/coco-ssd to devDependencies
- Update @rollup/plugin-terser to 1.0.0
