我来对这个 changelog 进行审查：

1. 格式规范：

• changelog 的基本格式符合 Debian 标准，包含了版本号、发行版、紧急程度和变更记录
• 每个变更条目都有正确的前缀（fix/feat/refactor）
• 维护者信息和日期格式正确

2. 内容质量：

• 变更描述清晰，涵盖了多个重要修复和改进
• 使用了统一的 commit message 前缀（fix/feat/refactor）

改进建议：

1. 日期问题：

• 日期显示为 2026 年 1 月 4 日，这明显是一个未来的日期，应该更正为实际日期

2. 描述规范：

• 有些条目可以更具体，比如 "Remove unused code" 可以说明具体移除了哪些代码
• "fix error on Archlinux build" 可以描述具体是什么错误
• 建议将相关的修复组合在一起，比如所有 Archlinux 相关的修复放在一起

3. 格式统一：

• 有些条目首字母大写，有些小写，建议统一为小写
• "fix: fix flash black on login" 中重复了 "fix"，建议改为 "fix: flash black screen on login"

4. 版本号：

• 确认版本号 0.3.0 是否符合项目的版本控制策略

建议修改后的格式示例：

ddm (0.3.0) unstable; urgency=medium

  * fix: flash black screen on login
  * fix: dde-session not start after treeland logged in
  * fix: dde-session not started after ddm restart & crash recovery
  * fix: Xwayland not started after crash recover & switch user
  * fix: enable Xauth access control for X11 sessions
  * fix: remove WAYLAND_DEBUG environment variable in release builds
  * fix: ddm & treeland startup issues on Archlinux
    - fix build errors on Archlinux
    - fix runtime errors on Archlinux
  * feat: apply systemd.exec limit options
  * refactor: display logic
  * refactor: PAM authenticate module
  * refactor: remove unused helper code

这样的修改使 changelog 更加清晰、专业，并且更容易追踪和理解具体的变更内容。
