Release version 0.12.3

• fix(web): command authentication failures now return as command errors without invalidating the Web session, so valid browser sessions stay signed in.
• fix(db): Tauri debug builds now use an isolated codeg-dev.db, avoiding SQLite conflicts with installed release builds during local development.
• chore(pet): pet sprite animation timing has been aligned across states for smoother idle, action, and review animations.

发布版本 0.12.3

• 修复(Web)：命令执行中的认证失败现在会作为业务错误返回，不再误判为 Web 会话失效，已登录的浏览器会话不会被登出。
• 修复(数据库)：Tauri 调试构建现在使用独立的 codeg-dev.db，本地开发时不会和已安装的正式版共享同一个 SQLite 数据库。
• 调整(桌宠)：桌宠精灵图动画节奏已重新对齐，待机、动作和审查等状态播放更自然。
