Release Notes v3.0.0

English

This is a preview release for a major 3.0.0 upgrade, not a stable rollout.

The desktop workflow has been substantially reworked around project-based translation, guided onboarding, and a more complete Tauri desktop experience.
Incremental translation is now backed by dedicated preparation, diff, snapshot, archive, build, package, and translation services.
The frontend now includes a fuller initial-translation flow, stronger project validation, richer history/activity views, and better in-app guidance.
Backend and integration coverage were expanded across project management, system utilities, archive handling, proofreading, and workshop flows.
The repository was cleaned up for public presentation by removing tracked temporary artifacts, replacing machine-specific paths with configurable scripts, and shipping a safe .env.example.

Please treat this build as a major-version transition and expect some rough edges.
Existing workflows should be more complete, but some behavior may differ from the 2.x series because of the architecture refactor.
If you run into bugs, migration issues, unclear UX, or unexpected translation results, please open an issue and include logs or reproduction steps when possible.
If anything is confusing, that feedback is also valuable. Questions and bug reports are both welcome.

这是一次面向重大升级的 3.0.0 预览版发布，不是稳定版正式发布。

桌面端工作流进行了较大重构，核心方向是项目化翻译、内置引导和更完整的 Tauri 桌面体验。
增量翻译链路已经拆分为 preparation、diff、snapshot、archive、build、package、translation 等独立服务模块。
前端补全了初始翻译流程、项目校验、历史/活动展示和更多引导式体验。
后端与集成测试覆盖扩展到了项目管理、系统能力、归档处理、校对能力和 workshop 流程。
为了让仓库更适合公开展示，也顺手清理了一批临时产物、本机硬编码路径和不必要的开发残留，并补充了安全的 .env.example。
