1. instead of mod prefix, let's follow the mapping/DOM ecosystem conventions for deltas with a suffixBy so modPitch > pitchBy, modRotation > rotateBy

2. you should add rotation normalization of 0-360 and pitch clamping to MapLibre's range of 0-85 to avoid returning weird numbers

3. Add tests for this new request (clamping / normalization behavior),

4. The MDX file for the camera needs to be updated to reflect these new functions
