Subject: 领域方案库 Cube 页面支持选择页面样式库样式后生成（方案级，镜像站点机制）
X-Git-Url: http://acesimba.cloud/gitweb/?a=commitdiff_plain;h=04fba162b2066f13b1807fcb69c3e1fd7d187e66;p=StationBuilder.git

领域方案库 Cube 页面支持选择页面样式库样式后生成（方案级，镜像站点机制）

- 后端 domain_templates 新增 style_id 列（ensureColumn 增量加列）；handleDomainTemplateUpdate 支持写入/显式置空；hydrateDomainTemplateCtx 返回真实 style_id
- 前端领域方案详情「功能与菜单 → Cube 扩展页面」顶部新增「领域方案页面样式」选择器（复用 .style-picker 与样式库缩略图），选中即持久化，生成/AI 修改经共享 buildStylePrompt 自动注入所选样式主题
- 设计文档升 v0.21，补充 changelog 与交互说明
