修复说明

开机后 XDG_CURRENT_DESKTOP 环境变量注入晚于门户前端（xdg-desktop-portal）启动，导致 FileChooser 接口缺失，Electron 应用选择文件夹时整窗闪退。

变更内容

• 新增 dde-session-environment.service（oneshot），在 graphical-session-pre.target 之前执行，提前将 XDG_CURRENT_DESKTOP=DDE 注入 systemd user manager 和 D-Bus activation environment
• 新增 dde-session-environment.sh 脚本，通过 systemctl --user set-environment 和 dbus-update-activation-environment 设置环境变量
• 在 main.cpp 中添加注释说明环境变量的双重注入策略

Summary by Sourcery

Inject XDG_CURRENT_DESKTOP=DDE earlier in the user session to prevent xdg-desktop-portal startup races.

Bug Fixes:

• Prevent portal startup races by injecting XDG_CURRENT_DESKTOP=DDE before the graphical session begins, restoring FileChooser availability for Electron applications.

Enhancements:

• Preserve the existing session environment initialization for the remaining desktop and display environment variables.

Build:

• Install and enable the new early session environment service and its setup script as part of the systemd user-session configuration.

Reviewer's Guide

通过新增并提前启动 systemd user oneshot 服务，将 XDG_CURRENT_DESKTOP=DDE 同时注入 user manager 与 D-Bus activation 环境，从启动时序上避免 xdg-desktop-portal 竞态；原有会话初始化继续负责完整环境变量配置及当前进程的 qputenv。

在图形会话早期阶段通过 systemd user service 提前注入 XDG_CURRENT_DESKTOP，避免门户前端启动竞态。	新增 oneshot 服务并挂接到 graphical-session-pre.target，调用环境设置脚本。 同时更新 systemd user manager 和 D-Bus activation environment，确保后续服务继承变量。 在构建和安装流程中生成、安装服务、脚本及 target wants 链接。	systemd/dde-session-environment.service.in systemd/dde-session-environment.sh.in systemd/CMakeLists.txt
保留会话进程内的完整环境初始化，并明确其与早期注入的职责边界。	为 EnvironmentsManager::init() 增加注释，说明 XDG_CURRENT_DESKTOP 的提前注入及当前进程环境设置仍不可省略。	src/dde-session/main.cpp
