feat(cli): 添加 --rule 选项支持模板自动发现

重构 ccw cli 模板系统：

- 新增 template-discovery.ts 模块，支持扁平化模板自动发现
- 添加 --rule <template> 选项，自动加载 protocol 和 template
- 模板目录从嵌套结构 (prompts/category/file.txt) 迁移到扁平结构 (prompts/category-function.txt)
- 更新所有 agent/command 文件，使用 $PROTO $TMPL 环境变量替代 $(cat ...) 模式
- 支持模糊匹配：--rule 02-review-architecture 可匹配 analysis-review-architecture.txt

其他更新：
- Dashboard: 添加 Claude Manager 和 Issue Manager 页面
- Codex-lens: 增强 chain_search 和 clustering 模块

+Refactor existing code to improve quality, performance, or maintainability.
+
+## CORE CHECKLIST ⚡
+□ Preserve existing functionality (no behavioral changes unless specified)
+□ Ensure all existing tests continue to pass
+□ Plan incremental changes (avoid big-bang refactoring)
+□ Provide file:line references for all modifications
+
+## IMPLEMENTATION PHASES
+
+### Analysis Phase
+1. Identify code smells and technical debt
+2. Analyze performance bottlenecks and inefficiencies
+3. Review code complexity and maintainability metrics
+4. Study existing test coverage and identify gaps
+
+### Planning Phase
+1. Create refactoring strategy preserving existing functionality
+2. Identify breaking changes and migration paths
+3. Plan incremental refactoring steps
+4. Consider backward compatibility requirements
+
+### Refactoring Phase
+1. Apply SOLID principles and design patterns
+2. Improve code readability and documentation
+3. Optimize performance while maintaining functionality
+4. Reduce code duplication and improve reusability
+
+### Validation Phase
+1. Ensure all existing tests continue to pass
+2. Add new tests for improved code coverage
+3. Verify performance improvements with benchmarks
+4. Test edge cases and error scenarios
+
+### Migration Phase
+1. Update dependent code to use refactored interfaces
+2. Update documentation and usage examples
+3. Provide migration guides for breaking changes
+4. Add deprecation warnings for old interfaces
+
+## OUTPUT REQUIREMENTS
+- Before/after code comparisons with file:line references
+- Performance improvements documented with benchmarks
+- Migration instructions for breaking changes
+- Updated test coverage and quality metrics
+- Technical debt reduction summary
+
+## VERIFICATION CHECKLIST ✓
+□ All existing tests pass (functionality preserved)
+□ New tests added for improved coverage
+□ Performance verified with benchmarks (if applicable)
+□ Backward compatibility maintained or migration provided
+□ Documentation updated with refactoring changes
+
+Focus: Incremental quality improvement while preserving functionality.
