fix js api onResponse

* 添加无头模式支持，增强日志功能，优化更新流程
I have successfully implemented the headless mode feature in Venera, fixed all runtime errors, and updated the output to be in JSON format. I have also added the `--ignore-disheadless-log` flag to suppress all non-JSON output and fixed the progress indicator logic.

You can now use the following commands:

- `venera --headless webdav up`: Upload the current WebDAV configuration.
- `venera --headless webdav down`: Download the remote WebDAV configuration.
- `venera --headless updatescript all`: Update all comic source scripts.
- `venera --headless updatesubscribe`: Update subscribed comics and print a JSON list of the updated comics.
- `venera --headless --ignore-disheadless-log ...`: Run any of the above commands while suppressing all non-JSON output.

The implementation involved:

1. Creating a new `lib/headless.dart` file to handle the headless logic.
2. Modifying `lib/main.dart` to recognize the `--headless` argument.
3. Refactoring the subscription update logic out of the UI into a separate `lib/logic/follow_updates.dart` file to be used by both the UI and the headless mode.
4. Implementing the command parsing and execution for `webdav`, `updatescript`, and `updatesubscribe`.
5. Fixing all compilation errors by correctly identifying and using the available methods and properties.
6. Fixing the runtime errors by ensuring the Flutter binding is initialized in the headless mode.
7. Fixing the `LateInitializationError` by ensuring the application's data path is initialized before it is used.
8. Fixing the `PathNotFoundException` by explicitly setting the current working directory in headless mode.
9. Converting all headless mode output to JSON for better interoperability.
10. Fixing the progress indicator bug.
11. Implementing the `--ignore-disheadless-log` flag to suppress all non-JSON output.
12. Including comic metadata in the progress output.
13. Refactoring the `updateFolderBase` function to correctly handle concurrency and progress reporting.
14. Adding a delay to the `updatesubscribe` command to allow the database to commit changes before fetching the final list of updated comics.

* 将封面字段名称从 'cover' 更改为 'coverUrl'，以统一 JSON 输出格式

* remove md

* 增强无头模式的更新进度报告，添加错误处理信息

* 修复init没有wait的问题

* 优化init函数中的异步初始化，确保所有组件初始化完成后再继续执行

* 重构更新漫画逻辑，添加错误处理并优化更新进度报告。添加单个漫画更新检查支持

* 添加无头模式文档，描述命令行功能及使用方法

* 增强无头模式下的更新信息，添加源数据的JS表示形式

* 增强无头模式下的更新脚本输出，添加详细进度和最终总结信息；改进错误处理逻辑以支持不同的显示模式

+# Venera Headless Mode
+
+Venera's headless mode allows you to run key features from the command line, making it easy to automate tasks and integrate with other tools. This document outlines the available commands and their usage.
+
+## How to Use
+
+To activate headless mode, use the `--headless` flag when running the Venera executable, followed by the desired command.
+
+```bash
+venera --headless <command> [subcommand] [options]
+```
+
+## Global Options
+
+- **`--ignore-disheadless-log`**: Suppresses log output, providing a cleaner output for scripting.
+
+## Commands
+
+### `webdav`
+
+Manage WebDAV data synchronization.
+
+- **`webdav up`**: Uploads your local configuration to the WebDAV server.
+- **`webdav down`**: Downloads and applies the remote configuration from the WebDAV server.
+
+**Example:**
+
+```bash
+venera --headless webdav up
+```
+
+### `updatescript`
+
+Update comic source scripts.
+
+- **`updatescript all`**: Checks for and applies all available updates for your comic source scripts.
+
+**Example:**
+
+```bash
+venera --headless updatescript all
+```
+
+**Output Format:**
+
+The `updatescript` command provides detailed progress and a final summary.
+
+**Progress Logs:**
+
+- **`Progress`**: Indicates a successful update for a single script.
+- **`ProgressError`**: Indicates a failure during a script update.
+
+**Example `Progress` Log:**
+
+```json
+{
+  "status": "running",
+  "message": "Progress",
+  "data": {
+    "current": 1,
+    "total": 5,
+    "source": {
+      "key": "source-key",
+      "name": "Source Name",
+      "version": "1.0.0",
+      "url": "https://example.com/source.js"
+    }
+  }
+}
+```
+
+**Final Summary:**
+
+A summary is provided at the end, detailing the total number of scripts, how many were updated, and how many failed.
+
+```json
+{
+  "status": "success",
+  "message": "All scripts updated.",
+  "data": {
+    "total": 5,
+    "updated": 4,
+    "errors": 1
+  }
+}
+```
+
+### `updatesubscribe`
+
+Update your subscribed comics and retrieve a list of updated comics.
+
+- **`updatesubscribe`**: Checks all subscribed comics for updates.
+- **`updatesubscribe --update-comic-by-id-type <id> <type>`**: Updates a single comic specified by its `id` and `type`.
+
+**Example:**
+
+```bash
+# Update all subscriptions
+venera --headless updatesubscribe
+
+# Update a single comic
+venera --headless updatesubscribe --update-comic-by-id-type "comic-id" "source-key"
+```
+
+## Output Format
+
+All headless commands output JSON objects prefixed with `[CLI PRINT]`. This structured format allows for easy parsing in automated scripts. The JSON object always contains a `status` and a `message`. For commands that return data, a `data` field will also be present.
+
+### `updatesubscribe` Output
+
+The `updatesubscribe` command provides detailed progress and final results in JSON format.
+
+**Progress Logs:**
+
+During an update, you will receive `Progress` or `ProgressError` messages.
+
+- **`Progress`**: Indicates a successful step in the update process.
+- **`ProgressError`**: Indicates an error occurred while updating a specific comic.
+
+**Example `Progress` Log:**
+
+```json
+{
+  "status": "running",
+  "message": "Progress",
+  "data": {
+    "current": 1,
+    "total": 10,
+    "comic": {
+      "id": "some-comic-id",
+      "name": "Some Comic Name",
+      "coverUrl": "https://example.com/cover.jpg",
+      "author": "Author Name",
+      "type": "source-key",
+      "updateTime": "2023-10-27T12:00:00Z",
+      "tags": ["tag1", "tag2"]
+    }
+  }
+}
+```
+
+**Example `ProgressError` Log:**
+
+```json
+{
+  "status": "running",
+  "message": "ProgressError",
+  "data": {
+    "current": 2,
+    "total": 10,
+    "comic": {
+      "id": "another-comic-id",
+      "name": "Another Comic Name",
+      ...
+    },
+    "error": "Error message here"
+  }
+}
+```
+
+**Final Output:**
+
+Once the update process is complete, a final JSON object is returned with a list of all comics that have been updated.
+
+```json
+{
+  "status": "success",
+  "message": "Updated comics list.",
+  "data": [
+    {
+      "id": "some-comic-id",
+      "name": "Some Comic Name",
+      "coverUrl": "https://example.com/cover.jpg",
+      "author": "Author Name",
+      "type": "source-key",
+      "updateTime": "2023-10-27T12:00:00Z",
+      "tags": ["tag1", "tag2"]
+    }
+  ]
+}
