feat(skills): add CCW orchestrator and refactor command-guide to ccw-help

CCW Skill (new):
- Stateless workflow orchestrator with intent classification
- 6 workflow combinations: rapid, full, coupled, bugfix, issue, ui
- External configuration: intent-rules.json, workflow-chains.json
- Implicit CLI tool injection (Gemini/Qwen/Codex)
- TODO tracking integration for workflow progress

CCW-Help Skill (refactored from command-guide):
- Renamed command-guide → ccw-help
- Removed reference folder duplication
- Source paths now relative from index/ (../../../commands/...)
- Added all-agents.json index
- Simplified SKILL.md following CCW pattern

+# Action: Rapid Workflow
+
+快速迭代工作流组合：多模型协作分析 + 直接执行
+
+## Pattern
+
+```
+lite-plan → lite-execute
+```
+
+## Trigger Conditions
+
+- Complexity: Low to Medium
+- Intent: Feature development
+- Context: Clear requirements, known implementation path
+- No uncertainty keywords
+
+## Execution Flow
+
+```mermaid
+sequenceDiagram
+    participant U as User
+    participant O as CCW Orchestrator
+    participant LP as lite-plan
+    participant LE as lite-execute
+    participant CLI as CLI Tools
+    
+    U->>O: Task description
+    O->>O: Classify: rapid
+    O->>LP: /workflow:lite-plan "task"
+    
+    LP->>LP: Complexity assessment
+    LP->>CLI: Parallel explorations (if needed)
+    CLI-->>LP: Exploration results
+    LP->>LP: Generate plan.json
+    LP->>U: Display plan, ask confirmation
+    U->>LP: Confirm + select execution method
+    
+    LP->>LE: /workflow:lite-execute --in-memory
+    LE->>CLI: Execute tasks (Agent/Codex)
+    CLI-->>LE: Results
+    LE->>LE: Optional code review
+    LE-->>U: Execution complete
+```
+
+## When to Use
+
+✅ **Ideal scenarios**:
+- 添加单一功能（如用户头像上传）
+- 修改现有功能（如更新表单验证）
+- 小型重构（如抽取公共方法）
+- 添加测试用例
+- 文档更新
+
+❌ **Avoid when**:
+- 不确定实现方案
+- 跨多个模块
+- 需要架构决策
+- 有复杂依赖关系
+
+## Configuration
+
+```javascript
+const rapidConfig = {
+  explorationThreshold: {
+    // Force exploration if task mentions specific files
+    forceExplore: /\b(file|文件|module|模块|class|类)\s*[:：]?\s*\w+/i,
+    // Skip exploration for simple tasks
+    skipExplore: /\b(add|添加|create|创建)\s+(comment|注释|log|日志)/i
+  },
+  
+  defaultExecution: 'Agent',  // Agent for low complexity
+  
+  codeReview: {
+    default: 'Skip',  // Skip review for simple tasks
+    threshold: 'medium'  // Enable for medium+ complexity
+  }
+}
+```
+
+## Example Invocations
+
+```bash
+# Simple feature
+ccw "添加用户退出登录按钮"
+→ lite-plan → lite-execute (Agent)
+
+# With exploration
+ccw "优化 AuthService 的 token 刷新逻辑"
+→ lite-plan -e → lite-execute (Agent, Gemini review)
+
+# Medium complexity
+ccw "实现用户偏好设置的本地存储"
+→ lite-plan -e → lite-execute (Codex)
+```
+
+## Output Artifacts
