fix(agent): inject Shanghai time into each reply message

103 goosed harness_remember returns remembered:false, so session memory never carried the time anchor. Prepend buildCurrentTimeAgentPrefix on every H5 /reply and WeChat agent prompt so the model sees Asia/Shanghai clock. Co-authored-by: Cursor <cursoragent@cursor.com>

 - 分支：`0630007-agent-time-fix`（从 `0630007-memind` 切出，**不含** miniapp / 0630006 改动）
 - 修复：向 Agent 注入 `TKMind 当前时间基准`（Asia/Shanghai），避免回复里报 UTC 时间
+- **v2**：103 上 `harness_remember` 返回 `remembered:false`，仅靠 harness 不可靠；改为在每条 `/reply` 用户消息里直接注入时间前缀（不依赖 harness）
