fix: convert cf-kv and excalidraw-libraries from submodules to regular files

- Remove stale cloudflare-worker submodule entry from .gitmodules
- Remove .git dirs from cf-kv and excalidraw-libraries so Git tracks them as regular files
- Fixes 'No url found for submodule path cf-kv' CI error

+# Excalidraw Cloudflare Worker 部署指南 (Dashboard 版)
+
+本文档将指导您如何通过 Cloudflare 的网页管理后台 (Dashboard) 部署 Excalidraw 后端服务。
+
+该 Worker 使用 Cloudflare 的 Durable Objects 来持久化存储画布数据，为您提供一个高性能、可扩展的 Excalidraw 后端服务。
+
+## 部署方法概述
+
+我们提供两种通过 Cloudflare Dashboard 部署的方法：
+
+1.  **通过 Git 仓库部署 (推荐)**: 设置一次后，每当您更新代码到 Git 仓库时，Cloudflare 都会自动为您部署最新版本。这是实现 CI/CD 的最佳实践。
+2.  **手动复制粘贴代码**: 简单快速，适合一次性测试或不希望关联 Git 仓库的场景。每次更新都需要手动操作。
+
+---
+
+### 方法一：通过 Git 仓库部署 (推荐)
+
+此方法将您的 GitHub 仓库与 Cloudflare 直接关联。
+
+#### 第一步：Fork 仓库
+
+1.  登录您的 GitHub 账户。
+2.  访问 `excalidraw-complete` 项目仓库，并点击右上角的 **Fork** 按钮，将项目复刻到您自己的账户下。
+
+#### 第二步：在 Cloudflare 中创建并连接应用
+
+1.  登录到您的 [Cloudflare Dashboard](https://dash.cloudflare.com/)。
+2.  在左侧导航栏中，选择 **Workers & Pages**。
+3.  点击 **Create application**，然后切换到 **Pages** 标签页，并点击 **Connect to Git**。
+4.  选择您刚刚 Fork 的项目仓库，并点击 **Begin setup**。
+
+#### 第三步：配置构建与部署
+
+1.  **Project name**: 为您的项目取一个名字。
+2.  **Production branch**: 选择 `main` 或者您 Fork 后的主分支。
+3.  **Build settings**:
+    -   **Framework preset**: 设置为 `None`。
+    -   **Build command**: *留空*。
+    -   **Build output directory**: *留空*。
+    -   **Root Directory**: 点击 `(Advanced)` 展开，设置为 `cloudflare-worker`。 **这一步至关重要**，它告诉 Cloudflare 只部署该子目录下的 Worker。
+4.  点击 **Save and Deploy**。Cloudflare 会开始第一次部署。
+
+#### 第四步：配置 Worker 的环境变量与存储
+
+首次部署完成后，我们需要为 Worker 添加必要的配置。
+
+1.  在项目页面，点击 **Settings** 标签页。
+2.  **设置 API 密钥**:
+    -   选择子菜单中的 **Variables**。
+    -   在 **Secret Variables** 部分，点击 **Add secret variable**。
+    -   **Variable name**: `API_TOKEN`
+    -   **Value**: 输入一个您自己创建的、足够复杂的安全密钥。**请务必保存好这个值**，前端配置时需要用到。
+    -   点击 **Save**。
+
+#### 第五步：重新部署以应用配置
+
+为了让刚才的配置生效，需要触发一次新的部署。
+
+1.  返回到项目的 **Deployments** 标签页。
+2.  找到最新的那条部署记录，点击右侧的 **...** 菜单，选择 **Retry deployment**。
+
+部署成功后，在项目主页即可找到您的 Worker 访问 URL。
+
+---
+
+### 方法二：手动复制粘贴代码
+
+此方法无需关联 Git 仓库，但每次更新代码都需要手动操作。
+
+#### 第一步：获取 Worker 代码
+
+1.  首先，将本项目克隆到您的本地电脑，以便获取 Worker 的源代码。
+    ```bash
+    git clone https://github.com/your-username/excalidraw-complete.git
+    # 注意：请将 a-username/excalidraw-complete.git 替换为实际的项目仓库地址
+    ```
+2.  在您的电脑上找到并打开 `cloudflare-worker/index.js` 文件，将其中的所有代码复制到剪贴板。我们稍后会用到它。
+
+#### 第二步：在 Cloudflare Dashboard 中创建 Worker
+
+1.  登录到您的 [Cloudflare Dashboard](https://dash.cloudflare.com/)。
+2.  在左侧导航栏中，选择 **Workers & Pages**。
+3.  点击 **Create application**，然后选择 **Create Worker**。
+4.  为您的 Worker 指定一个唯一的名称（例如 `my-excalidraw-backend`），然后点击 **Deploy**。
+
+#### 第三步：粘贴并部署代码
+
+1.  创建成功后，您会进入 Worker 的管理页面。点击 **Edit code**。
+2.  在打开的代码编辑器中，删除所有的默认 "Hello World" 代码。
+3.  将您在 **第一步** 中从 `index.js` 文件复制的代码，完整地粘贴到编辑器中。
+4.  点击编辑器右上角的 **Save and Deploy** 按钮。
+
+#### 第四步：设置 API 密钥 (Secret Variable)
+
+1.  返回到您的 Worker 管理页面 (如果当前在代码编辑器，可以点击左上角 Worker 名称返回)。
+2.  选择 **Settings** 标签页，然后点击子菜单中的 **Variables**。
+3.  在 **Secret Variables** 部分，点击 **Add secret variable**。
+4.  按如下方式填写：
+    -   **Variable name**: `API_TOKEN`
+    -   **Value**: 输入一个您自己创建的、足够复杂的安全密钥（例如，可以使用密码生成器创建一个长随机字符串）。**请务必保存好这个值，前端配置时需要用到。**
+5.  点击 **Save**。
+
+#### 第五步：配置持久化存储 (Durable Objects)
+
+这是最关键的一步，它让您的 Worker 能够保存数据。
+
+1.  在 Worker 的 **Settings** 标签页，点击子菜单中的 **Durable Objects**。
+2.  点击 **Add binding**。
+3.  按如下方式创建第一个绑定：
+    -   **Binding name**: `CANVAS_OBJECT`
+    -   **Durable Object class name**: `CanvasObject`
+4.  再次点击 **Add binding**。
+5.  按如下方式创建第二个绑定：
+    -   **Binding name**: `INDEX_OBJECT`
+    -   **Durable Object class name**: `IndexObject`
+6.  完成后，页面上应该有两个 Durable Object 绑定。设置会自动保存。
+
+#### 第六步：最终确认
+
+设置完变量和存储后，建议返回代码编辑器，再次点击 **Save and Deploy**，以确保所有配置都已生效。
+
+部署成功后，在 Worker 的主页面可以找到您的 Worker 的访问URL，格式为 `https://<your-worker-name>.<your-subdomain>.workers.dev`。
+
+---
+
+## 配置 Excalidraw 前端
+
+现在，将您部署好的后端服务配置到 Excalidraw 前端：
+
+1.  打开 Excalidraw 应用。
+2.  进入设置或数据源配置界面。
+3.  选择 "Cloudflare KV" 作为存储类型。
+4.  **API 地址**: 填入您在第六步获取的 Worker URL。
+5.  **API 令牌**: 填入您在第四步中设置的 `API_TOKEN` 值。
+6.  保存配置。
+
+恭喜！您的 Excalidraw 应用现在拥有了一个完全由您掌控、基于 Cloudflare 的强大后端。

+
+## Create your own library
+
+1. Open [Excalidraw](https://excalidraw.com/) and draw some objects.
+2. Optional: Make sure every object is it's own group (by selecting it and clicking "Group selection" or `Ctrl`+`G`).
+3. Add each object you want in your library like so:
+
+- Select the object
+- Open the library menu (by clicking on the "library" button or typing `9`)
+- The selected object should appear in a square. Click on it (you will see a `+` sign when hovering over it)
+
+4. Still in the library menu, select the libraries you want to publish (hover over a library item and you should see a checkbox, clicking on which will select the library item).
+
+5. Hit the publish button (in blue), and fill out the details.
+
+![Gif showing how to add a single object and export the library](public/submit-lib-for-review.gif)
+
+If you want to test your library file, use the "Load" button in the library menu to reimport it.
+
+## Guidelines
+
+1. Don't submit a library that's only for your personal use case, and will not be useful to others.
+2. Don't submit items which are easy to create directly. For example, a single arrow or a square.
+3. Don't republish (copy/paste) items from other libraries without making any significant changes.
+4. We only accept libraries in English. This includes any texts/labels, and library description and titles. (In the future, we may accept other languages.)
+5. In general, each item should be usable and stand on its own. (In the future we'll support filtering and installing items individually.)
+6. In general, a library should be composed of at least 3 items, and the items should be related to each other (be in a single category).
+7. If a library item consists of multiple elements, you should group them together so that the item acts as a single unit when inserting on canvas. Exception being templates or if you really think it works better if ungrouped.
+
+Check out our existing [libraries](https://libraries.excalidraw.com/?theme=light&sort=default) to get started.
+
+Once the library is submitted for review, changes may be requested if the guidelines above are not followed or the quality doesn't meet the standards of the published libraries.
