EMP v0.13.0

中文

前端（10 项）：

• 将已确认的 Shadow 界面迁入正式版，两者共用静态资源。
• 额度圆环作为新设置的默认样式，保留已选横条／圆环与不限额显示。
• 紧凑账户信息与累计 Token／USD，统一服务详情页签。
• 返回与关闭按钮统一无边框，保留父窗口返回与取消行为。
• 连接表单简化标签；已保存 API Key 显示六星占位，输入新值可见，空值或取消保留旧 Key。
• 模型管理按服务查看、搜索、显示／隐藏、编辑、手动添加和测试，移除重复的隐藏主页列表。
• 订阅上下文说明区分目录默认值、上限和 Codex 可用比例，编辑时更新计算。
• 每个模型可暂存向其他订阅同步显示与上下文，保存时一起提交；使用直双箭头与按键形状 Reset。
• 数据迁移按服务／模型选择并在导入预览调整名称，一次导入提交；关闭保留原配置，演示只读。
• 更新窗口显示安全渲染的中英说明；统计纵轴按实际峰值保留 5% 余量。

后端（8 项）：

• HTTP 上游协商 gzip／Brotli／Zstandard／deflate 压缩响应并流式解码，保留解码后大小限制、超时与显式 identity。原生请求压缩和增量 WS 保持兼容。
• 正式迁移预览使用有容量、期限和会话边界的私有缓存，凭据不返回浏览器；选中项才进入加密导出与事务导入。
• 迁移按账户／连接身份合并，区分同名服务并同步映射模型、显示名与凭据引用。
• 额度辅助进程避免重复下载模型目录，原生 OAuth 轮换由规范凭据所有者处理。
• 重试和协议回退计入所属请求，排除 WebSocket 预热的推理调用与用量。
• 原生恢复会关闭闲置 WebSocket 后等待活动请求；退出只恢复配置，不批量改写会话。
• 新增明确指定会话的 migrate-history --thread-id，保留备份并拒绝该会话的活动写入。
• 用量读取使用持久身份映射，错误说明保留来源、原始代码与定向历史修复建议。

整理与验证：拆分连接、订阅、更新及 HTTP 回应生命周期；删除重复资源、运行时函数替换与退役控件测试。保留可观察行为、取消、凭据与回滚测试；构建缓存和测试配置减少重复工作。

Frontend (10 changes):

• Promote the accepted Shadow UI to the formal frontend with shared static assets.
• Default new preferences to quota rings while preserving chosen styles and unlimited displays.
• Compact account information and lifetime Token/USD totals; unify service detail tabs.
• Use borderless Back/Close controls with parent navigation and cancellation.
• Simplify connection labels. Saved keys use a six-star placeholder; replacements stay visible, while blank saves and cancellation preserve the key.
• Manage/search/show/hide/edit/add/test models per service; remove the duplicate hidden homepage list.
• Explain catalog defaults, maxima and usable-context percentages with live calculations.
• Stage per-model visibility/context synchronization to other subscriptions until Save; use straight opposing arrows and a physical Reset icon.
• Select migration services/models and rename incoming services in one import flow. Closing preserves configuration; demos are read-only.
• Show safely rendered bilingual release notes; scale statistics to the measured peak plus 5%.

Backend (8 changes):

• Negotiate gzip/Brotli/Zstandard/deflate upstream HTTP responses with streaming decoding, decoded limits, deadlines and explicit identity support. Preserve native request compression and incremental WS compatibility.
• Keep formal migration previews in bounded, expiring, session-bound private storage; never return credentials to the browser. Encrypt/export and transactionally import selected items.
• Merge migrations by account/connection identity and map models, aliases and credential references together.
• Avoid repeated quota-helper catalog downloads; settle native OAuth rotation through its canonical credential owner.
• Account retries/protocol fallback within their request; exclude WS prewarm from inference and usage.
• Drain idle WebSockets before native restoration and wait for active requests. Exit restores configuration without bulk history rewriting.
• Add explicit migrate-history --thread-id with backups and active-writer protection for the selected conversation.
• Project usage through durable identity mappings; preserve error origins/codes and targeted history-repair guidance.

Cleanup and validation: separate connection, subscription, update and HTTP-response lifecycle owners. Remove duplicate assets, runtime function replacement and retired-control tests. Retain behavioral, cancellation, credential and rollback coverage; reduce repeated work with build caching and test profiles.
