Version: 0.9.81.dev.260506

后端：
1. Credit 价格规则补齐利润率与实际计费单价语义：新增 `profit_rate_bps` 与 `charge_*_price_micros` 展示字段，下沉共享价格推导 helper，tokenstore rpc/client/proto/model/default rule 全链路同步，LLM usage 扣费统一改按加价后的 charge 单价换算。
2. task-class 更新链路修正全量覆盖与归属校验：`runtime/conv` 保留 item id，DAO 更新前显式校验 task-class 与 item 归属，改用显式字段 map 落库 nil/空切片/零值，避免 `RowsAffected=0` 误判越权，同时补齐任务项可编辑字段更新。
3. GormCache task-class 失效补空 user_id 保护：更新语句缺少模型上下文时直接跳过失效，避免缓存插件因空指针影响主事务。

前端：
4. 课表中心补齐任务类编辑能力：新增 `updateTaskClass` API，创建弹窗支持编辑态回填与 item id 提交，日程页支持先拉详情再编辑并在保存后刷新任务类详情与列表。
5. 计划广场详情补点赞交互与奖励提示：详情页新增点赞/取消点赞按钮、奖励反馈文案与计数展示，论坛类型补 `reward_hint`，评论区与帖子作者头像统一接入兜底头像工具。
6. 品牌与展示细节收口：侧边栏与 favicon 切到项目 logo，首页标题改为 `SmartMate`，主面板缩放上限微调，论坛列表头像显示与整体品牌观感同步统一。
