CarsRUS: session car history – stick to discussed models on follow-up

CarsRUS: Link & Co 01 normalization (and/לינק&קו), tests

RAG: better normalization for Genesis GV80 + Link & Co Hebrew; add test_chat_scenarios manual script

OpenRouter: default model google/gemini-3-flash-preview (fix 404, gemini-2.0-flash-exp:free deprecated)

Generation: use only OpenRouter when OPENROUTER_API_KEY set (no Gemini fallback)

OpenRouter: log when key missing; try more env names; doc HF secret OPENROUTER_API_KEY

OpenRouter first (faster), Gemini fallback; conversation history Q+A; optional .env

Pipeline logging + show LLM response in chat

Rate limit: longer retries (8 attempts, 3 min wait); show as 'בעיה זמנית' not 'התשובה'

Present aggregated verbal answer first in chat; strengthen RAG prompt

UI/UX: RTL layout, dark mode, stable header logo, chat/input RTL, scrollbar, focus states; agent: retrieve→generate→end, final answer separator

Fix: Hebrew Elantra N detection, final answer display, stronger prompts; UI redesign; Hebrew comparison test

RAG: comparison by supported models, partial answer for 1 known model, stronger prompts for context aggregation

🔧 Fix: Smarter rate limit handling - wait 30s on 429 errors instead of switching models

✅ Improve: Increase minimum delay to 3s + more aggressive exponential backoff (3^n) for rate limit handling

✅ Fix: Add rate limiting with exponential backoff + response caching to prevent API quota errors

✅ Fix: Update to correct Gemini API models (gemini-2.0-flash, gemini-1.5-flash, gemini-1.5-pro) + Clean minimal chat UI

🔧 Fix: Dark chat UI + correct Gemini API model names

🎨 Simplify UI to clean professional design + 🐛 Add better error handling
