QVAC-18794 test: skip multi-gpu tests on mobile

[Victor-Rodzko]

🎯 What problem does this PR solve?

• multi-gpu-config-smoke reliably crashes the Android consumer in the full SDK smoke suite (native SIGABRT inside libqvac__llm-llamacpp.so), red-blocking CI on every smoke run.
• Multi-GPU is not a supported deployment target on mobile (single-GPU devices). Per Gianfranco's call in the QVAC-18794 thread, the cleanest fix is to remove multi-gpu-* from the mobile test surface entirely rather than keep an Android-only skip.
• The crash itself is on the addon side (Adreno OpenCL backend state pollution from prior LLM inference) and is tracked separately in QVAC-18794.

📝 How does it solve it?

• Add SkipExecutor(/^multi-gpu-/, ...) to the mobile-wide skip block in packages/sdk/tests-qvac/tests/mobile/consumer.ts (alongside finetune-, tools-, etc.), covering both Android and iOS.
• Remove the MultiGpuExecutor import and handler from the mobile consumer (now dead code on mobile).
• Desktop multi-gpu coverage is unaffected.

🧪 How was it tested?

With the skip applied — full smoke on all platforms green:

• ✅ https://github.com/tetherto/qvac/actions/runs/25673774199 — Android, iOS, Ubuntu, Windows, macOS all pass (validated the Android-only variant; mobile-wide removal is a strict superset of that skip, so iOS behaviour is unchanged from a passing baseline).

Diagnostics — three Android runs on the same SHA family, same llm-llamacpp@0.18.0 prebuild, same tensor-split: "1,1" config; only the preceding test set differs:

• ❌ Full smoke (~91 tests): https://github.com/tetherto/qvac/actions/runs/25667547912/job/75345105724 — multi-gpu-config-smoke crashes the consumer ~5 s after start (SIGABRT via ggml_abort in ggml_backend_sched_new); tombstone in artifact device-farm-logs-android-android-98275cd-75343917571.
• ✅ multi-gpu-* only: https://github.com/tetherto/qvac/actions/runs/25676619728 — both pass (3993 ms / 32916 ms).
• ✅ model,multi-gpu filter (13 model-* tests + 2 multi-gpu-*): https://github.com/tetherto/qvac/actions/runs/25717007197 — all 15 pass.

Local: bun run lint (eslint + typecheck) clean in packages/sdk.
