PrivyTranslate: AI Translator

Version 0.6.5 makes PrivyTranslate far smaller to download, guides you through a one-time on-device model setup, and adds a terminology glossary, Turbo mode, and an optional Professional model. - Removed the bundled translation model, cutting the app download to a small fraction of its previous size. - Added a guided first-run screen that downloads the free Standard model on device, with progress, cancel, and resume. - Made the free Standard model a lighter TranslateGemma build, chosen for a smaller download and lower memory use on iPhone and iPad. - Kept the screen awake while a model downloads, so a large transfer is never interrupted by the display going to sleep. - Made model downloads survive interruptions: a download resumes where it stopped after a cancel, a quit, or an unexpected shutdown. - Added Professional: a one-time in-app purchase that unlocks the higher-quality TranslateGemma 4B model for download. - Added a terminology glossary as a Professional feature: pin your preferred translation for a term and PrivyTranslate applies it consistently across translations. - Added Turbo mode, which translates short text with Apple's fast on-device translation. Single words always use it; longer snippets are opt-in. - Added a Local context window setting so you can trade memory for handling longer passages on device. - Added Restore Purchases so a reinstalled Professional upgrade comes back without a repurchase. - Added a startup check that finds the installed model, and repairs the setting if a model was moved or removed. - Changed Settings to show the model's name, such as TranslateGemma 4B (Standard), instead of its file name. - Raised the system requirement to iOS 18, which Apple's on-device translation needs.
