refactor: remove summarizeToolOutput feature

Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>

Remove the summarizeToolOutput setting and related functionality.

This feature allowed LLM-based summarization of shell tool output but is no longer needed.

This simplifies the codebase by removing unused summarization logic and configuration options.
