feat(team): integrate refined team tool and align with upstream

- Merge feat/team: integrate multi-agent orchestration tool into main.
- Fix Team Tool bugs: resolve DAG goroutine leaks and token budget clamping.
- Optimize Team strategies: implement text-only evaluator and partial parallel success.
- Enhance observability: add structured logging and improved user summaries.
- Expand configuration: add max_context_runes and reviewer_model settings.
- Refactor context builder: implement cached system prompt and simplified dynamic context.
- Align with upstream: remove local Embedding support and custom truncation logic for better parity.
- Documentation: update tools_configuration.md with detailed Team tool guide.
