feat: 角色视觉体系（头像按角色取）+ 时间注入（loop 每轮当前时间）

【角色视觉体系（红线：每个角色自己的头像/背景，绝不串用昔涟）】
- persona.go：Persona 加 Visual{avatar, chatBackground{landscape,portrait}} + DefaultAvatar；每个角色各自配。
- cyrene.yaml：昔涟配 avatar(3F-Q-Happy-1) + chatBackground(横/竖屏)。
- PersonaStore 加 Persona(id)；PersonaSummary 加 avatar/chatBackground；collectPersonas 按角色取
  Persona(id) 视觉（无视觉→空，前端回退默认占位，绝不串角色）。
- 前端：types PersonaRecord 加 avatar/chatBackground；persona.ts personaAvatar(p)=p?.avatar||默认占位
  (殊无昔涟 fallback)；store 加 currentPersona；App 挂载 fetchPersonas 取默认角色；
  TopBar/chat 头像改 personaAvatar(currentPersona)（写死昔涟头像已清除）。

【时间注入（她自然知道现在几点，深夜催睡交给人格/capacity）】
- options.go Options 加 Timezone；loop.go Loop 加 timeLocation/timeZoneName + New 解析 + loadTimezone；
  time.go currentTimeBlock()(当前时间+周几+时区，每轮刷新)；memory.go assembleContext 在「工作记忆」
  前注入时间 system(keyed 在 timeLocation!=nil，无时区不注入不破坏测试)；wire.go Timezone=a.cfg.Timezone。

go build/vet/test 全绿(gateway/loop/persona)；前端 tsc/vite build 75模块绿。红线无写死昔涟头像。
