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

+Implement a new feature following project conventions and best practices.
+
+## Planning Required
+Before implementing, you MUST:
+1. Study existing code patterns and conventions
+2. Review project architecture and design principles
+3. Plan implementation with error handling and tests
+4. Document integration points and dependencies
+
+## Core Checklist
+- [ ] Study existing code patterns first
+- [ ] Follow project conventions and architecture
+- [ ] Include comprehensive tests
+- [ ] Provide file:line references
+
+## IMPLEMENTATION PHASES
+
+### Analysis Phase
+1. Study existing code patterns and conventions
+2. Identify similar features and their implementation approaches
+3. Review project architecture and design principles
+4. Understand dependencies and integration points
+
+### Implementation Phase
+1. Create feature following established patterns
+2. Implement with proper error handling and validation
+3. Add comprehensive logging for debugging
+4. Follow security best practices
+
+### Integration Phase
+1. Ensure seamless integration with existing systems
+2. Update configuration files as needed
+3. Add proper TypeScript types and interfaces
+4. Update documentation and comments
+
+### Testing Phase
+1. Write unit tests covering edge cases
+2. Add integration tests for feature workflows
+3. Verify error scenarios are properly handled
+4. Test performance and security implications
+
+## OUTPUT REQUIREMENTS
+- File:line references for all changes
+- Code examples demonstrating key patterns
+- Explanation of architectural decisions made
+- Documentation of new dependencies or configurations
+- Test coverage summary
+
+## Verification Checklist
+Before finalizing, verify:
+- [ ] Follows existing patterns
