chore(release): bump version to 1.3.4-6 (Beta) + 修 Linux CI fcitx5-dev 安装

v1.3.4-4 / -5 的 Linux 构建在 "Build fcitx5 plugin" 步骤连挂两次，
错误一致："E: Unable to locate package fcitx5-dev"。同一 job 前面的
"Install Linux bundle deps" 步骤明明已经 apt-get update + 装好了一堆
universe 包，到 fcitx5 这步突然找不到 —— 表象与 GitHub Actions
ubuntu-22.04 runner 镜像弃用过渡期里 apt 元数据漂移的现象一致。

release-tauri.yml "Build fcitx5 plugin" 步骤增加三层防御：
  1) sudo add-apt-repository -y universe（已启用则 no-op）
  2) 本步骤内重新 sudo apt-get update，独立于上游 step 缓存
  3) 安装失败时打印 apt-cache policy / search / os-release / sources.list.d
     便于以后排查

同 commit 同时 bump 五处版本到 1.3.4-6 重发，让 PR #487/#488/#489
三个 Windows P0 修复带上 Linux 包一起进 Beta 通道。
