V-Proofix v1.2 release

CHANGELOGS

• Translate Hotkey (Ctrl + Alt + T): Added a global hotkey to translate selected text directly.
• New Translate Window: Introduced a dedicated translation UI with a readable output area, scrolling, Copy/Close buttons, and Esc to close.
• 300-word output cap: Translation output is limited to 300 words for concise and stable display behavior.
• Separate target language settings by feature: Added independent settings for Fix Target Language, Translate Target Language, and Summary Target Language.
• Automatic settings migration: Existing settings are migrated automatically to preserve user configuration.

Translation AI Improvements

• Humanized translation prompt: Upgraded prompting to prioritize context and intent, avoiding word-by-word translation.
• Natural tone preservation: Keeps output fluent and native-sounding, especially for social/community-style text.
• Format preservation: Keeps markdown, line breaks, bullets, links, code, commands, paths, and proper nouns intact.
• Fallback model + retry: Translation now uses the same resilient model fallback and retry pipeline as other AI features.

UI/UX Improvements

• No direct replace on translate: Translation results are shown in a popup so users can review and copy manually.
• Word count indicator in translate window: Displays count as x / 300 for clear output-limit visibility.
• Additional localization strings: Added translation-related labels for title, buttons, and status text.
