docs: document the community fork, bilingual README + license + modification notes

- README.md / README.zh.md: add a bilingual "community fork" banner noting this is a
  derivative of deepseek-ai/deepseek-harness with a desktop app, plugin marketplace,
  image recognition, and a release channel; link to the modification notes.
- MODIFICATIONS.md / MODIFICATIONS.zh.md: standard, bilingual list of changes vs upstream.
- LICENSE: keep MIT, add PineSound as derivative copyright holder while preserving the
  original DeepSeek copyright, and point to MODIFICATIONS.md.

+# Modifications — Community Fork of deepseek-harness
+
+This repository is a **community fork** of
+[deepseek-ai/deepseek-harness](https://github.com/deepseek-ai/deepseek-harness) (MIT),
+maintained by PineSound. The core harness — plugin architecture, agent loop,
+server, and web frontend — is **preserved unchanged**; the fork adds a desktop
+application and related product capabilities.
+
+- **Upstream**: https://github.com/deepseek-ai/deepseek-harness (MIT)
+- **This fork**: adds `apps/desktop`, new host/client packages, and a release channel
+- **License**: [MIT](LICENSE), with the original copyright preserved
+- **Desktop repo**: https://github.com/PineKings/deepseek-harness-desktop
+- **Publish site**: https://deepseek.pinesound.cn/
+
+## Major changes vs. upstream
+
+### 1. Desktop app (`apps/desktop`, deepseek-harness-desktop)
+- An Electron shell that launches the real `dsh` (the `web` profile) on loopback and opens a native window, so no browser tab or manual URL is needed.
+- Self-contained: the packaged app bundles the full harness runtime, vendored pnpm, and a platform Node — zero external dependencies on the target machine.
+- Cross-platform installers: macOS (`.dmg`) and Windows (`.nsis`).
+- Chinese application menu and branded icons.
+
+### 2. Plugin inventory & marketplace (`packages/host/plugin-inventory`)
+- Visual plugin list with search, status, and enable/disable controls.
+- Black/whitelist guard: required system plugins cannot be disabled.
+- Plugin install from npm / tarball / GitHub via the built-in pnpm, with multi-mirror fallback and hot reload (no restart).
+- A plugin marketplace with persistent install state and priority-based ordering.
+
+### 3. Skill manager (`packages/host/skill-manager`)
+- Manage local skills from the settings UI: list, install, uninstall, enable/disable, and edit descriptions.
+
+### 4. Image recognition / vision
+- An OpenAI-compatible HTTP vision provider (e.g. Alibaba DashScope) that fills the gap for text-only models.
+- Vision key / endpoint / model are configured independently of the chat model.
+- A settings **namespace exposure** mechanism (`configurable` + `exposeSettings`) lets third-party settings namespaces be edited from the UI.
+
+### 5. Update & release channel
+- The About page shows the dynamic version and "check for updates", reading an online `releases.json`.
+- Desktop updates and the web publish site share the same manifest — one deploy publishes both.
+
+## Scope preserved
+
+The fork does **not** change the harness backend. The desktop is a thin launcher;
+native addons keep their system Node ABI and are never loaded under Electron.

+# 更改说明 — deepseek-harness 社区版
+
+本仓库是 [deepseek-ai/deepseek-harness](https://github.com/deepseek-ai/deepseek-harness)(MIT)
+的**社区衍生版**,由 PineSound 维护。核心 harness——插件架构、agent loop、服务端、前端——**完全保留不变**;
+本仓库在其基础上新增了桌面应用与相关产品能力。
+
+- **上游**: https://github.com/deepseek-ai/deepseek-harness(MIT)
+- **本仓库**: 新增 `apps/desktop`、若干 host/client 包与发布渠道
+- **协议**: [MIT](LICENSE),保留原项目版权
+- **桌面仓库**: https://github.com/PineKings/deepseek-harness-desktop
+- **发布站**: https://deepseek.pinesound.cn/
+
+## 相比上游的主要改动
+
+### 1. 桌面应用(`apps/desktop`,即 deepseek-harness-desktop)
+- 基于 Electron 的桌面外壳,启动真正的 `dsh`(`web` 配置)于回环端口并打开原生窗口,无需浏览器标签页或手动输入 URL。
+- 自包含:安装包内置完整 harness 运行时、vendored pnpm 与平台 Node,目标机器**零外部依赖**。
+- 跨平台安装包:macOS(`.dmg`)与 Windows(`.nsis`)。
+- 中文应用菜单与品牌图标。
+
+### 2. 插件清单与插件市场(`packages/host/plugin-inventory`)
+- 可视化插件列表,支持搜索、状态查看与启用/停用。
+- 黑白名单守卫:核心系统插件不可停用。
+- 经内置 pnpm 从 npm / tarball / GitHub 安装插件,多镜像回退、免重启实时生效。
+- 插件市场:持久化安装状态、按优先级排序。
+
+### 3. 技能管理(`packages/host/skill-manager`)
+- 在设置页管理本机技能:列表、安装、卸载、启用/停用、编辑描述。
+
+### 4. 图像识别 / 视觉能力
+- 通过 OpenAI 兼容 HTTP 视觉提供方(如阿里云 DashScope)为纯文本模型补齐视觉能力。
+- 视觉的密钥 / 接口 / 模型与对话主模型**完全独立**配置。
+- 新增 settings **命名空间暴露**机制(`configurable` + `exposeSettings`),可在界面编辑第三方 settings 命名空间。
+
+### 5. 更新与发布渠道
+- 「关于」页显示动态版本号与「检查更新」,读取线上 `releases.json`。
+- 桌面更新与网页发布站读取**同一份**清单,一次发布同时服务桌面与网页。
+
+## 保留范围
+
+本仓库**不改变 harness 后端**。桌面仅是薄启动器;原生插件仍运行在系统 Node ABI 上,从未加载进 Electron。

 DeepSeek Harness (`dsh`) is an open-source agent harness developed by [DeepSeek AI](https://deepseek.com).
 
 It uses an architecture where **everything is a plugin**, and is powered by [Cordis](https://github.com/cordiverse/cordis), whose design is described in [_A Programming Paradigm for Spatiotemporal Composability_](https://github.com/cordiverse/paper).

 DeepSeek Harness（`dsh`）是由 [DeepSeek AI](https://deepseek.com) 开发的开源 agent harness（智能体框架）。
 
 它采用**一切皆插件**的架构，并由 [Cordis](https://github.com/cordiverse/cordis) 驱动，其设计参见论文 [_A Programming Paradigm for Spatiotemporal Composability_](https://github.com/cordiverse/paper)。
