feat(v2.5.0-beta): Complete MCP Tool Optimization

- Optimize all 25 MCP tools with XML structure and LLM guidance
- Fix addressbook_query inefficiency (3x calls -> 1x call)
- Add PREFERRED/WARNING labels for efficient tool selection
- Implement delete_event workflow guidance (calendar_query first)
- Fix parameter validation for empty parameters
- Add next-action hints in formatters
- Enhance test infrastructure with better validation and logging
- Add comprehensive test cases with optimal_route definitions

Performance: Token efficiency improved, LLM tool selection optimized
Compatibility: Server-specific bugs documented and workarounds provided
