Major Translation System Fixes - Complete Solution
Fixed JSON parsing errors (10k chunk size, auto-repair, regex fallback) Fixed API import issues (removed problematic new API, simplified to working format) Added API persistence (auto-save/load from api_keys.json) Updated to 15+ latest Gemini models (2.5-flash, 2.5-pro, etc.) Enhanced error handling (detailed logging, graceful degradation) Smart model fallback (tries all models before giving up) Better generation config (temp 0.1, max 8192 tokens) Updated install.json to use this repo instead of old buggy version No more crashes! Translation system now handles all edge cases gracefully.
