Update config.example.yaml

fix(project): 允许 fact_key 驼峰命名并澄清未绑定项目授权报错 (#200 ) (#217 )
- fact_key 校验放开大写字母，支持驼峰命名（如 finding/info-disclosure-messageBundle）： - internal/database/project.go: 正则 ^[a-z0-9]... 改为 ^[a-zA-Z0-9]...，并更新错误提示 - internal/project/fact_body_links.go: body 解析正则（依赖事实/相关 fact_key）同步放开大写 - authorizeProjectTool 区分「未绑定项目 / 查询出错 / 真实无权限」三种情况：未绑定项目时返回明确可执行提示，替代误导性的 no access to project - internal/app/mcp_authorization.go Co-authored-by: sycmacmini <sycmacmini@sycmacminis-Mac-mini.local>
