Artificial.py Refactoring - Phase 1 Complete ✅

Successfully refactored the monolithic 3,760-line `artificial.py` file into **24 focused, modular files** organized into **7 distinct packages**. This represents approximately **75% completion** of the planned refactoring, with all low-to-medium risk modules extracted and operational. #### `utils/retry.py` - **Functions:** - `create_retry_decorator(max_retries)` - Tenacity-based retry decorator - `retry_api_call(api_func, max_retries, *args, **kwargs)` - Generic retry wrapper - `backoff_handler(attempt)` - Exponential backoff calculation - `log_handler(message)` - Retry logging #### `utils/validation.py` - **Functions:** - `validate_image_response(image_response)` → (revised_prompt, image_url) - `validate_audio_response(audio_response)` → bool - `validate_text_response(text_response)` → bool #### `utils/text_utils.py` - **Functions:** - `get_verbosity()` → bool - `similarity_score(text1, text2)` → float (0-1) - `clean_text(text)` → str - `truncate_text(text, max_length, suffix)` → str - `extract_code_blocks(text)` → List[str] #### `embeddings/generator.py` - **Class:** `EmbeddingGenerator` - `__init__(embedder)` - `generate_embeddings(prompts: List[str])` → embeddings
