Subject: [PATCH 1/2] chore(cloudxr): bump runtime SDK version to 6.3.0-rc3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to #873, which landed 6.3.0-rc2. rc3 is the newest runtime
published on NGC (cloudxr-dev/cloudxr-runtime-binary:6.3.0-rc3-public,
uploaded 2026-07-31) and, unlike earlier versions, it also publishes the
experimental tarballs the cloudxr_exp bundle needs.

The SDK is consumed as prebuilt shared objects only — CMake extracts the
tarball and drops include/ and plugins/ — so nothing in the tree compiles
or links against it and the pin is the whole change.

Subject: [PATCH 2/2] ci: bundle the experimental CloudXR runtime in
 build-ubuntu

Configure build-ubuntu with ENABLE_CLOUDXR_EXP_BUNDLE=ON so CI wheels carry
isaacteleop.cloudxr_exp with its native runtime. The option's default stays
OFF: the experimental tarball ships on private NGC until a version goes GA,
so a keyless source build cannot obtain it.

setup-cloudxr-sdk now requests it as well. That step holds the job's only NGC
key, and the configure step re-runs the same script without one, so anything
not staged there cannot be fetched later. Paired with the existing
ENABLE_CLOUDXR_BUNDLE_CHECK=ON, a version that stops publishing the tarball
fails the build rather than silently shipping a wheel without it.
