Summary: Keep a stable owning global JNI reference in the context container and expose a borrowed alias under the existing `FabricUIManager` key. Use alias reads for synchronous Android Fabric measurement, colour resolution and image prefetching, avoiding global-reference allocation and release on each lookup. Add instrumentation coverage for exact alias/owner handle identity, mixed legacy global-ref and alias readers, and legacy-copy validity after the aliased handle owner is released. Stale global-ref readers still depend on the current fbjni wrapper representation; these tests exercise that compatibility, not a type-safe C++ guarantee.
