fix: enhance filename extraction logic for downloads and add unit tests

- Updated command usage in English and Simplified Chinese localization files to reflect changes in transfer command syntax.
- Removed batch import task implementation, replacing it with a new transfer task implementation.
- Introduced new task structure and progress tracking for file transfers.
- Updated task type enumeration to replace batch import with transfer.
- Added new fields in data structures to support transfer operations.
- Implemented file handling and progress reporting for the transfer task.

+- `remove_after_transfer`: Whether to remove local files downloaded by Aria2 after transfer, default is `true`

 ### Storage Endpoints List

+## Direct Download Links
+
+Use the `/dl` command to directly download one or more HTTP/HTTPS files to storage.
+
+```bash
+/dl <url1> [url2] [url3] ...
+```
+
+Examples:
+
+```bash
+/dl https://example.com/file.zip
+/dl https://example.com/file1.zip https://example.com/file2.zip
+```

+
+{{< hint warning >}}
+This feature requires enabling Aria2 in the configuration file and configuring the RPC connection.
+{{< /hint >}}
+
+Use the `/aria2dl` command to download files via the Aria2 download manager, supporting HTTP/HTTPS, FTP, BitTorrent, and other protocols.
+
+```bash
+/aria2dl <uri1> [uri2] [uri3] ...
+```
+
+Examples:
+
+```bash
+# Download HTTP link
+/aria2dl https://example.com/file.zip
+
+# Download magnet link
+/aria2dl magnet:?xt=urn:btih:...
+
+# Download torrent file (need to upload .torrent file first)

+secret = "your-rpc-secret"  # If rpc-secret is configured

+## yt-dlp Video Download
+
+{{< hint warning >}}
+This feature requires the yt-dlp command-line tool installed on your system.
+{{< /hint >}}
+
+Use the `/ytdlp` command to download videos and audio from supported video websites, including YouTube, Bilibili, Twitter, and 1000+ other sites.
+
+```bash
+/ytdlp <url1> [url2] [flags...]
+```
+
+Examples:
+
+```bash
+# Basic download
+/ytdlp https://www.youtube.com/watch?v=dQw4w9WgXcQ
+
+# Download multiple videos
+/ytdlp https://www.youtube.com/watch?v=video1 https://www.youtube.com/watch?v=video2
+
+# Use custom parameters
+/ytdlp https://www.youtube.com/watch?v=dQw4w9WgXcQ -f best
+/ytdlp https://www.youtube.com/watch?v=dQw4w9WgXcQ --extract-audio --audio-format mp3
+```
+
+Common parameters:
+
+- `-f <format>`: Specify download format (e.g., `best`, `worst`, `bestvideo+bestaudio`)
+- `--extract-audio`: Extract audio
+- `--audio-format <format>`: Audio format (e.g., `mp3`, `m4a`, `wav`)
+- `--write-sub`: Download subtitles
+- `--write-thumbnail`: Download thumbnail
+
+For more parameters, see [yt-dlp documentation](https://github.com/yt-dlp/yt-dlp#usage-and-options).
+
+## Storage Transfer
+
+Use the `/transfer` command to transfer files directly between different storages without going through Telegram.
+
+```bash
+/transfer <source_storage>:/<source_path> [filter]
+```
+
+Parameters:
+
+- `source_storage`: Source storage name
+- `source_path`: Source path
+- `filter`: Optional regex filter to transfer only matching files
+
+Examples:
+
+```bash
+# Transfer entire directory
+/transfer local1:/downloads
+
+# Transfer files from specified path
+/transfer alist1:/media/photos
+
+# Transfer only mp4 files
+/transfer webdav1:/videos ".*\.mp4$"
+
+# Transfer image files
+/transfer local1:/pictures "(?i)\.(jpg|png|gif)$"
+```
+
+The bot will:
+
+1. List all files in the source path
+2. Apply the filter (if provided)
+3. Display file count and total size
+4. Ask you to select the target storage
+5. Ask you to select the target directory (if configured for that storage)
+6. Start the transfer task
+
+Notes:
+
+- Source storage must support listing and reading
+- Target storage must support writing
+- Real-time progress is displayed during transfer
+- Transfer tasks can be cancelled
+

 Besides files on Telegram, the bot can also save files from other websites via JavaScript plugins or built-in parsers.

+## 直接下载链接
+
+使用 `/dl` 命令可以直接下载一个或多个 HTTP/HTTPS 链接的文件到存储中.
+
+```bash
+/dl <url1> [url2] [url3] ...
+```
+
+示例:
+
+```bash
+/dl https://example.com/file.zip
+/dl https://example.com/file1.zip https://example.com/file2.zip
+```
+
+Bot 会验证链接格式, 然后让你选择目标存储位置.
+
+## Aria2 下载
+
+{{< hint warning >}}
+该功能需要在配置文件中启用 Aria2 并配置 RPC 连接.
+{{< /hint >}}
+
+使用 `/aria2dl` 命令可以通过 Aria2 下载管理器下载文件, 支持 HTTP/HTTPS、FTP、BitTorrent 等多种协议.
+
+```bash
+/aria2dl <uri1> [uri2] [uri3] ...
+```
+
+示例:
+
+```bash
+# 下载 HTTP 链接
+/aria2dl https://example.com/file.zip
+
+# 下载磁力链接
+/aria2dl magnet:?xt=urn:btih:...
+
+# 下载种子文件 (需要先上传 .torrent 文件)
+/aria2dl https://example.com/file.torrent
+```
+
+配置 Aria2:
+
+在 `config.toml` 中添加:
+
+```toml
+[aria2]
+enable = true
+url = "http://localhost:6800/jsonrpc"
+secret = "your-rpc-secret"  # 如果配置了 rpc-secret
+remove_after_transfer = true  # 转存完成后删除本地文件
+```
+
+## yt-dlp 视频下载
+
+{{< hint warning >}}
+该功能需要在系统中安装 yt-dlp 命令行工具.
+{{< /hint >}}
+
+使用 `/ytdlp` 命令可以下载支持的视频网站的视频和音频, 支持 YouTube、Bilibili、Twitter 等 1000+ 个网站.
+
+```bash
+/ytdlp <url1> [url2] [flags...]
+```
+
+示例:
+
+```bash
+# 基本下载
+/ytdlp https://www.youtube.com/watch?v=dQw4w9WgXcQ
+
+# 下载多个视频
+/ytdlp https://www.youtube.com/watch?v=video1 https://www.youtube.com/watch?v=video2
+
+# 使用自定义参数
+/ytdlp https://www.youtube.com/watch?v=dQw4w9WgXcQ -f best
+/ytdlp https://www.youtube.com/watch?v=dQw4w9WgXcQ --extract-audio --audio-format mp3
+```
+
+常用参数:
+
+- `-f <format>`: 指定下载格式 (如 `best`, `worst`, `bestvideo+bestaudio`)
+- `--extract-audio`: 提取音频
+- `--audio-format <format>`: 音频格式 (如 `mp3`, `m4a`, `wav`)
+- `--write-sub`: 下载字幕
+- `--write-thumbnail`: 下载缩略图
+
+更多参数请参考 [yt-dlp 文档](https://github.com/yt-dlp/yt-dlp#usage-and-options).
+
+## 存储间传输
+
+使用 `/transfer` 命令可以在不同存储之间直接传输文件, 无需经过 Telegram.
+
+```bash
+/transfer <source_storage>:/<source_path> [filter]
+```
+
+参数说明:
+
+- `source_storage`: 源存储名称
+- `source_path`: 源路径
+- `filter`: 可选的正则表达式过滤器, 只传输匹配的文件
+
+示例:
+
+```bash
+# 传输整个目录
+/transfer local1:/downloads
+
+# 传输指定路径的文件
+/transfer alist1:/media/photos
+
+# 只传输 mp4 文件
+/transfer webdav1:/videos ".*\.mp4$"
+
+# 传输图片文件
+/transfer local1:/pictures "(?i)\.(jpg|png|gif)$"
+```
+
+Bot 会:
+
+1. 列出源路径下的所有文件
+2. 应用过滤器 (如果提供)
+3. 显示文件数量和总大小
+4. 让你选择目标存储
+5. 让你选择目标目录 (如果该存储配置了目录)
+6. 开始传输任务
+
+注意:
+
+- 源存储必须支持列举和读取功能
+- 目标存储必须支持写入功能
+- 传输过程显示实时进度
+- 支持取消正在进行的传输任务
+
 ## 转存 Telegram 之外的文件
 
 除了 Telegram 上的文件, Bot 还可通过 JavaScript 插件或内置解析器来支持转存其他网站的文件.
