Upgrade rig-core from 0.27 to 0.33 and adapt to its API changes:
- Rename multi_turn() to max_turns() in DynAgent prompt calls
- Access prompt_response.usage instead of .total_usage
- Destructure StreamedAssistantContent::ToolCall as struct variant

Update default models: OpenAI gpt-5.1 → gpt-5.4, Anthropic
claude-sonnet-4-5 → claude-opus-4-6. Bump 25+ other dependencies
to latest (reqwest 0.13, tokio 1.50, serde 1.0.228, opaline 0.4,
strum 0.28, toml 1.1, etc). Update CLAUDE.md model table.
