docs: 在任务生成命令中添加focus_paths路径清晰度准则

在三个任务生成命令中添加核心准则：
- task-generate.md
- task-generate-tdd.md
- task-generate-agent.md

路径要求：
- 优先使用绝对路径（如 D:\project\src\module）
- 或使用从项目根目录的清晰相对路径（如 ./src/module）
- 避免模糊的相对路径（如 analysis, interfaces）

更新示例JSON展示混合使用两种路径方式

 - **Agent Simplicity**: Agent receives pre-selected template and focuses only on content generation
+- **Path Clarity**: All `focus_paths` prefer absolute paths (e.g., `D:\\project\\src\\module`), or clear relative paths from project root (e.g., `./src/module`)
