- Extract duplicated LLM client code from 4 engines into utils/llm_provider.py - Auto-detect token type: OpenAI SDK, Anthropic API key, or Claude Code OAuth - Each engine's llms/base.py now inherits from the unified client - Add anthropic SDK to requirements.txt - Update ForumEngine, KeywordOptimizer, TopicExtractor to use unified client - Fix pinned versions (Pillow, matplotlib) for broader compatibility Reduces ~700 lines of duplicated boilerplate code across engines.
