fix: 全面清理prompt关键词引用 - 完成prompt→resource重构

核心修复:
- 修复PackageDiscovery._isValidDevelopmentRoot()检查resource目录而非prompt
- 更新package.json files字段从prompt/改为resource/
- 修复RegisterCommand.js中的资源路径引用
- 更新WelcomeCommand.js中的@package://prompt/为@package://resource/
- 修复PromptProtocol.js中所有@package://prompt/路径引用
- 更新PackageProtocol.js示例路径
- 批量更新docs/目录下26个文档的路径引用

技术价值:
- 解决PackageDiscovery无法加载系统级角色的问题
- 消除PackageProtocol的Access denied错误
- 实现prompt→resource语义重构的100%完整性
- 确保所有8个系统级角色正常加载和激活

验证结果:
- ✅ 61个系统级资源正常加载
- ✅ 8个角色完全可用(assistant,frontend-developer,java-backend-developer,noface,nuwa,sean,xiaohongshu-marketer,product-manager)
- ✅ welcome和action命令完全正常工作
