优化: token消息级持久化 + 技能注入修复 + TopBar减法/UI调

token持久化(方案A,治压缩/切会话后历史token不显):ChatMessage/AiMessageRecord 加 prompt_tokens/completion_tokens(serde + DB V38 迁移 + message_repo 映射);agentic push_assistant_message 设本轮 token + provider/title 构造默认 None;前端 AiMessage 加字段 + switchConversation reload 映射 tokenUsage(双轨:消息级新+会话级旧累计保留)

技能注入修复:read_skill_content_stripped 改 skills_cached 扫盘(防御 SKILLS None 致不注入)+ 细化诊断(缓存/path/fs 各步)

TopBar减法/UI:删铅笔新建(与侧栏+重复)/删垃圾桶clear-chat(危险,clear-context归档替代)/删系统就绪装饰占位;更多菜单popout CSS补全(修样式错乱);provider绿点有信息化(绿/红/灰基于AI请求成败)+垂直居中;goals面板补top:100%(修位置飘)+dot/check/remove CSS+goals/history item统一+history index边距;4面板互斥(点一个收其他)

MessageList token v-if 去 !streaming(修发新消息历史token消失)
