Description

• New translation task behind one Translator API (useTranslator, translate(text, { sourceLanguage, targetLanguage }, onToken?)).
• Opus-MT: six pairs (en↔de, en↔es, en↔fr), XNNPACK int8 only (fastest on S26 Ultra and iPhone 16; Core ML, MLX and Vulkan were slower).
• EuroLLM-1.7B-Instruct: any pair of its 35 languages with one model (XNNPACK 8da8w, MLX int8 on iOS); switching pairs does not reload it.
• Fix: LLM streaming dropped word breaks for tokenizers whose decoder strips a leading space (EuroLLM).
• NLP demo gets a Translation screen.
• Bumps nativeLibsVersion to 0.10.7 (v0.10.7-libs).
