📝 Walkthrough

Walkthrough

This PR downgrades the CloudXR SDK and associated React/Three.js libraries from version 6.2.0 to 6.1.0, aligning the Web SDK version across environment configuration, package metadata, and telemetry reporting. The dependency stack is correspondingly adjusted for compatibility. The PerformanceCanvasImage component (which rendered metrics as a canvas texture) is completely removed, and the performance metrics display in CloudXRUI is reimplemented using three stacked text-based metric cards.

6.2.0 SDK proven to have a regression that needs to be fixed first. We also should put a stable build to main instead of latest
