Refactor documentation for code commands and workflows

- Updated command syntax formatting to use code blocks for clarity in `prep.md`, `review.md`, and `spec.md`.
- Enhanced architectural diagrams in `ch01-what-is-claude-dms3.md` and core concepts in `ch03-core-concepts.md` using mermaid syntax for better visualization.
- Improved workflow diagrams in `ch04-workflow-basics.md` and `4-level.md` to provide clearer representations of processes.
- Added troubleshooting section in `installation.md` to address common installation issues and provide quick start examples.
- Revised skill documentation in `claude-meta.md` and `claude-workflow.md` to standardize command triggers and output structures.
- Updated best practices and workflow index documentation to enhance readability and understanding of workflow levels and practices.

+### 权限问题
+
+如果遇到权限错误：
+
+```bash
+# 使用 sudo（不推荐）
+sudo npm install -g claude-code-workflow
+
+# 或修复 npm 权限（推荐）
+mkdir ~/.npm-global
+npm config set prefix '~/.npm-global'
+export PATH=~/.npm-global/bin:$PATH
+```
+
+### PATH 问题
+
+将 npm 全局 bin 添加到您的 PATH：
+
+```bash
+# 对于 bash/zsh
+echo 'export PATH=$(npm config get prefix)/bin:$PATH' >> ~/.bashrc
+
+# 对于 fish
+echo 'set -gx PATH (npm config get prefix)/bin $PATH' >> ~/.config/fish/config.fish
+```

+## 快速开始示例
+
+安装完成后，尝试以下命令验证一切正常：
+
+```bash
+# 1. 在您的项目中初始化
+cd your-project
+ccw init
+
+# 2. 尝试简单的分析
+ccw cli -p "分析项目结构" --tool gemini --mode analysis
+
+# 3. 运行主编排器
+/ccw "总结代码库架构"
+
+# 4. 检查可用命令
+ccw --help
+```
+
+### 预期输出
+
+```
+$ ccw --version
+CCW v7.0.5
+
+$ ccw init
+✔ Created .claude/CLAUDE.md
+✔ Created .ccw/workflows/
+✔ Configuration complete
