v2.1.0

What's Changed

• Improved offline translation — TranslateGemma 4B and Qwen 2.5 1.5B as offline backends, with OpenCL acceleration, KV-cache reuse, memory-aware gating, and Settings UI to manage them. On devices with sufficient RAM.
• Translate multiple screens simultaneously — capture, overlays, floating icon, region picker, and live mode can all work for more than one display at a time. Great for DS and 3DS games!
• Anki export overhaul — Card Type picker with per-field mapping; Lapis/JPMN/Migaku presets; plain + furigana + pinyin variants for SENTENCE/EXPRESSION; deck moves apply to all generated cards.
• OCR improvements — diacritics preprocessing for Latin sources; sigmoid k=7 + auto-invert; center-alignment + hanging-punct compensation; OCR-only bypass when source equals target.
• Quick Settings tile to launch the floating overlay.
• Polish & fixes — Japanese dictionary v2 with better headword ranking and kana vs kanji display fixes for uk-tagged entries; restyled overlay dialogs (OverlayProgress, OverlayAlert); DeepL usage display; fixed accessibility-permission loss on restart; fixed WindowContext rotation race; Play Protect / restricted-accessibility troubleshooting in README.
