feat: add load file while load the dirs from the server.

[yyjeqhc]

1.mono服务器添加一个api，返回文件的hash值
2.添加ContentStorage，类似于TreeStorage,保存加载的文件内容到数据库
3.添加文件内容加载，当加载目录的时候，也会检测文件内容变化进行加载
4.添加文件内容加载测试，mono添加文件或者修改文件后，本地加载目录会更新文件内容。

• Using unwrap() here could lead to a panic if commit retrieval fails; it's recommended to handle the error gracefully.

let commits = self.get_commits_by_hashes(commit_ids.into_iter().collect()).await.unwrap();

ceres/src/api_service/mod.rs:238

• [nitpick] If the commented-out add_blobs_to_map block is no longer needed, consider removing it to improve code clarity.

// self.add_blobs_to_map(...).await;

[Copilot]

Avoid using unwrap() in production code as it may panic; consider propagating the error using proper error handling.

	// Ensure that the response status is successful
	if response.status().is_success() {
	// Get the binary data from the response body

	// Ensure that the response status is successful
	if response.status().is_success() {
	// Get the binary data from the response body
	let content = response.bytes().await.map_err(|e| DictionaryError {
	message: format!("Failed to read response bytes: {}", e),
	})?;
	return Ok(content.to_vec());
	}
	Err(DictionaryError {
	message: "Response status was not successful".to_string(),
	})

[Copilot]

[nitpick] Using sled in an async context might block the async runtime; consider offloading DB access to a blocking thread pool or switching to an async-compatible database driver.
