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

 - **Role Analysis-Driven**: All generated tasks originate from role-specific `analysis.md` files (enhanced in synthesis phase), ensuring direct link between requirements/design and implementation
 - **Artifact-Aware**: Automatically detects and integrates all brainstorming outputs (role analyses, guidance-specification.md, enhancements) to enrich task context
 - **Context-Rich**: Embeds comprehensive context (requirements, focus paths, acceptance criteria, artifact references) directly into each task JSON
+- **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`)
 - **Flow-Control Ready**: Pre-defines clear execution sequence (`pre_analysis`, `implementation_approach`) within each task
 - **Memory-First**: Prioritizes using documents already loaded in conversation memory to avoid redundant file operations
 - **Mode-Flexible**: Supports both agent-driven execution (default) and CLI tool execution (with `--cli-execute` flag)
