Summary

The workspace now names Spatial's checkout spatial/ (workspace#2), and scripts/build.sh builds it from there. virocore still looked only for ../reactvisioncca, and both Android and iOS fall back silently to stub cloud anchors when the headers are missing, so a renamed checkout would build without Spatial and no error.

What's in it

• Android (android/sharedCode/CMakeLists.txt): RVCCA_DIR is ../../../spatial, or ../../../reactvisioncca when only the old folder exists.
• iOS (ViroRenderer.xcodeproj): HEADER_SEARCH_PATHS lists ../../spatial/include before ../../reactvisioncca/include, in both configurations.
• Comments in VROCloudAnchorProviderReactVision.mm and build_visionos.sh name the new folder.

Notes

• Nothing else changes: the library is still libreactvisioncca, and the prebuilts stay in ios/Libraries/reactvisioncca/.
• The fallback keeps checkouts that have not renamed the folder building as before.

Testing

• plutil -lint on the project file passes; CI builds Android and iOS.
• After the merge, a full scripts/build.sh from the renamed spatial/ checkout, checking with scripts/verify_colocation_binaries.sh that the binaries carry Spatial, not the stubs.
