fix[Logger]: in renderer worker (#8284)

* docs: enhance LoggerService documentation and usage guidelines

- Added details about `initWindowSource` method, emphasizing its return of the LoggerService instance for method chaining.
- Introduced a section on using LoggerService within `worker` threads, highlighting the need to call `initWindowSource` first.
- Updated both English and Chinese documentation files to reflect these changes, ensuring clarity in usage instructions for developers.

* docs: update LoggerService documentation and improve environment checks

- Enhanced documentation for using LoggerService in worker threads, clarifying logging support limitations in main and renderer processes.
- Added environment checks for development and production modes directly in the LoggerService.
- Removed the unused env utility file to streamline the codebase.

* refactor(ShikiStreamService): update highlighter management and improve test assertions

- Modified the highlighter management in ShikiStreamService to clear the reference instead of disposing it directly, as it is now managed by AsyncInitializer.
- Enhanced unit tests to verify the initialization of worker and main highlighters, ensuring that either one is active but not both, and updated assertions related to highlighter disposal.

- An error will be thrown if `windowName` is not set, and the `logger` will not work.
- `windowName` can only be set once; subsequent attempts to set it will have no effect.
- `windowName` will not be printed in the `devTool`'s `console`, but it will be recorded in the `main` process terminal and the file log.
- `initWindowSource` returns the LoggerService instance, allowing for method chaining

## About `worker` Threads
- Currently, logging is not supported for workers in the `main` process.
- Logging is supported for workers started in the `renderer` process, but currently these logs are not sent to `main` for recording.
### How to Use Logging in `renderer` Workers
Since worker threads are independent, using LoggerService in them is equivalent to using it in a new `renderer` window. Therefore, you must first call `initWindowSource`.
If the worker is relatively simple (just one file), you can also use method chaining directly:
```typescript
const logger = loggerService.initWindowSource('Worker').withContext('LetsWork')
```
## Log Level Usage Guidelines
There are many log levels. The following are the guidelines that should be followed in CherryStudio for when to use each level:

| **`verbose`** | **More detailed flow information than `info`, used for tracing specific features.** <br> Enabled when diagnosing issues with a specific feature to help understand the internal execution flow. | - Loading `Toolbar` module. <br> - IPC message `open-file-dialog` sent from the renderer process. <br> - Applying filter 'Sepia' to the image. |

# 如何使用日志 LoggerService
这是关于如何使用日志的开发者文档。
CherryStudio使用统一的日志服务来打印和记录日志**若无特殊原因,请勿使用`console.xxx`来打印日志**
以下是详细说明
## 在`main`进程中使用
### 引入
@ -81,6 +81,7 @@ loggerService.initWindowSource('windowName')
- 未设置`windowName`会报错,`logger`将不起作用
- `windowName`只能设置一次,重复设置将不生效
- `windowName`不会在`devTool`的`console`中打印出来,但是会在`main`进程的终端和文件日志中记录
- `initWindowSource`返回的是LoggerService的实例因此可以做链式调用
### 记录级别
@ -120,6 +121,21 @@ logger.getLogToMainLevel()
logger.info('message', { logToMain: true })

## 关于`worker`线程
- 现在不支持`main`进程中的`worker`的日志。
- 支持`renderer`中起的`worker`的日志,但是现在该日志不会发送给`main`进行记录。
### 如何在`renderer`的`worker`中使用日志
由于`worker`线程是独立的在其中使用LoggerService等同于在一个新`renderer`窗口中使用。因此也必须先`initWindowSource`。
如果`worker`比较简单,只有一个文件,也可以使用链式语法直接使用:
```typescript
const logger = loggerService.initWindowSource('Worker').withContext('LetsWork')
```
## 日志级别的使用规范

| **`verbose`** | **比 `info` 更详细的流程信息,用于追踪特定功能。** <br> 在诊断特定功能问题时开启,帮助理解内部执行流程。 | - 正在加载 `Toolbar` 模块。 <br> - IPC 消息 `open-file-dialog` 已从渲染进程发送。<br> - 正在应用滤镜 'Sepia' 到图像。` |
