QVAC-18096 test[skiplog]: stabilize mobile e2e (skip afriquegemma on ios, raise c…

[Victor-Rodzko]

Note: be concise and prefer bullet points.

🎯 What problem does this PR solve?

• Smoke suite was red on every recent run across iOS, Android, Linux, Windows, macOS — mix of mobile OOM crashes, cold-load timeouts, an addon-contract bug in test code, and LLM nondeterminism.
• CI noise was masking real regressions; suite could not be used as a merge gate.

📝 How does it solve it?

All mobile — skip diffusion (packages/sdk/tests-qvac/tests/mobile/consumer.ts):

• ^diffusion- — SD v2.1 1B Q8_0 (~2.16 GB) cold-load reproducibly blocks the JS event loop for 300–600+ s, killing the consumer via heartbeat. iOS Device Farm is variable 5–15 min; Android trips the heartbeat. Replaces the older narrow diffusion-streaming-progress skip.

iOS only — skip OOM-bound models:

• ^translation-afriquegemma- — AfriqueGemma 4B Q4_K_M (~2.67 GB) SIGSEGVs during load on iPhone 16 Pro Device Farm.

Mobile timeout tuning:

• tts-chatterbox-short-text: 30 s → 200 s
• parakeet-ctc-mp3: 120 s → 200 s
• kv-cache-stats-verification: 30 s → 90 s

Mobile workflow timeouts (.github/workflows/test-sdk.yml):

• mobile-consumer-timeout default: 600 s → 1200 s
• device-farm-timeout default: 30 min → 90 min

Mobile heartbeat — add --consumer-inactivity-timeout workflow input to both test-android-sdk.yml and test-ios-sdk.yml (default 300 s), making it tunable instead of hardcoded 120 s.

Mobile TTS executor bug (packages/sdk/tests-qvac/tests/mobile/executors/tts-executor.ts):

• Was missing makeSentenceStream branch. tts-supertonic-sentence-stream was routed to the regular streaming handler and returned the wrong output format. Ported the method from the desktop executor.

TTS executor types (mobile + shared):

• Replace as unknown as { ... } casts with shared TtsParams / TtsResult = ReturnType<typeof textToSpeech> aliases. No behavior change; removes a class of silent contract drift between SDK return shape and tests.

Cross-platform — drop test-code flakes:

• kv-cache-streaming-sliding-window: replace contains-any: ["14"] with type: string. Test contract is "kv cache works with stream:true", not "1B model can do 7+7". Aligns with all sibling kv-cache tests.
• completion-stop-sequences: replace nondeterministic prompt ("List 10 fruits") with deterministic ("Repeat exactly: apple banana cherry"). Banana is now guaranteed in output; stop-sequence behavior exercised reliably.

Addon-busy retry (packages/sdk/tests-qvac/tests/shared/executors/logging-executor.ts):

• Wrap every completion() call in LoggingExecutor with callWhenAddonIdle, which absorbs the documented qvac-lib-infer-llamacpp-llm "a job is already set or being processed" busy throw with a 30 s deadline (then throws AddonBusyTimeoutError with cause). No SDK-side changes required.

🧪 How was it tested?

• Smoke suite: 7 consecutive CI runs on this branch from full-red → 4 of 5 platforms 100% green (Linux 100%, macOS 100%, Android 100%, iOS 100%). Windows occasionally fails on a separate cache-restore auth flake; rerun passes.
• Last green run: 25119457964.
• Local full-suite (382 tests) on iPhone 16 Pro Device Farm: 284 pass / 2 fail / 96 skip; both remaining fails (tts-supertonic-sentence-stream, completion-stop-sequences) are addressed in this PR.
• npx tsc --noEmit clean in packages/sdk/tests-qvac.
