- Ollama: pass tools to API, parse tool_calls responses, handle thinking field from reasoning models (deepseek-r1, glm-4.7-flash)
- llama.cpp: pass tools via OpenAI-compatible endpoint, parse tool_calls, accumulate streaming tool call deltas
- Both clients now set stopReason to 'tool_use' when tool calls are present
- Tests: 12 new tests (8 Ollama + 5 llama.cpp, total 983→995)
Widen Message.content from string to string | MessageContentPart[] to support
multimodal content. Add Attachment type to channel layer, media conversion
utilities, and image extraction to all channel adapters (Telegram, Discord,
Slack, WhatsApp). Update all model clients (Anthropic, OpenAI, Gemini, Bedrock)
to convert structured content to provider-specific formats. Fix downstream
consumers (tokens, compaction, TUI, local models) to handle the widened type
via getMessageText() helper.
