* maps webxr-device

Feature: WebXR
Reference: https://github.com/web-platform-dx/web-features/blob/main/features/webxr-device.yml

Note: The navigator.xr API represents the browser's virtual reality or augmented reality system. The core WebXR Device API includes XRSystem, XRSession, XRFrame, XRView, XRPose, XRViewerPose, XRInputSource, XRReferenceSpace, XRRigidTransform, XRWebGLLayer and related interfaces for requesting and managing XR sessions.

Search strategy: Searched for major WebXR interface names (navigator.xr, XRSession, XRFrame, XRView, XRPose, XRViewerPose, XRInputSource, XRReferenceSpace, XRRigidTransform, XRWebGLLayer, XRSystem).

WEB_FEATURES.yml files created:
✅ [webxr/WEB_FEATURES.yml](webxr/WEB_FEATURES.yml) - Core WebXR Device API tests (83 files) - **CREATED**

Excluded (42 files):
- WebXR extension subdirectories (30 files): anchors/ (6), ar-module/ (3), depth-sensing/ (10), dom-overlay/ (2), gamepads-module/ (1), hit-test/ (4), layers/ (2), light-estimation/ (2) - These are extension features that should be classified separately (webxr-anchors, webxr-hit-test, webxr-layers, webxr-lighting-estimation, etc.)
- Non-webxr tests (11 files): speculation-rules/prerender (4), permissions-policy/reporting (2), feature-policy/reporting (1), video-rvfc (2), resources/chromium (2) - Tests that incidentally reference WebXR
