Refactor architecture optimization and issue resolution workflows

- Enhanced multi-perspective discussion capabilities in discuss-subagent for architecture optimization, integrating CLI tools for structured analysis and recommendations.
- Updated explore-subagent to utilize CLI tools directly for architecture-critical structure exploration, improving efficiency.
- Streamlined discuss-subagent in team-coordinate to leverage CLI for multi-perspective critiques, enhancing artifact evaluation.
- Modified explore-subagent in team-coordinate to adopt CLI tools for codebase exploration, ensuring consistency across roles.
- Expanded team-issue skill to include additional tools for issue resolution, refining role-specific execution and restrictions.
- Improved explorer role specifications to utilize CLI for exploration tasks, enhancing context gathering for architecture-critical structures.
- Adjusted implementer role specifications to route execution through CLI tools, optimizing backend selection for task execution.
- Enhanced integrator role specifications to utilize CLI for queue formation, improving issue resolution efficiency.
- Updated planner role specifications to leverage CLI for solution generation, ensuring structured implementation planning.
- Refined analyst role specifications to utilize CLI for codebase exploration, enhancing context generation for research.
- Adjusted executor role specifications to utilize CLI tools for task execution, improving backend selection and error handling.
- Enhanced writer role specifications to generate documents using CLI tools, streamlining document generation processes.
- Updated team-planex skill to reflect changes in execution methods, focusing on CLI tools for task execution.
- Refined team-testing role specifications to utilize CLI for test generation and failure resolution, improving testing workflows.
- Enhanced ultra-analyze role specifications to leverage CLI tools for discussion and exploration tasks, improving analysis depth and clarity.
