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
