Introduces Provider::Anthropic alongside Provider::Openai, implementing the LlmConcept chat_response contract over the official anthropic Ruby SDK. Batch ops, PDF, and RAG land in follow-up PRs. - Provider::Anthropic uses Messages API for sync and streaming responses - ChatConfig builds requests with ephemeral prompt-cache markers on the system prompt and the last tool definition - MessageFormatter reconstructs multi-turn history (text + tool_use + tool_result blocks) from raw Message records, including the paired user-role tool_result turn Anthropic requires after every tool_use - ChatParser maps Anthropic Message into the shared ChatResponse Data - Registry, Setting, User, Chat default model wired for ANTHROPIC_* envs and Setting.anthropic_*; LLM_PROVIDER selects between providers - Responder forwards raw conversation_history (Array<Message>) so providers without hosted conversation state can rebuild context - OpenAI provider accepts and ignores the new kwarg (no behavior change) Tests cover provider init, model gating, MessageFormatter for all turn shapes, ChatConfig request building (max_tokens, system cache, tool conversion), ChatParser for text / tool_use / mixed blocks, Registry discovery, and mocked chat_response success / error / function_request paths. Live VCR cassettes recorded in a follow-up with a real key. Stacked PRs: 2/5 batch ops + cost ledger, 3/5 PDF, 4/5 pgvector RAG, 5/5 settings UI + disclosure.
