Subject: [PATCH] ``` feat(logger): add maxCount configuration option for file
 appender

Add support for maxCount parameter in file appender configuration.
The maxCount option allows users to specify the maximum number of
backup files to keep when log rotation is enabled.

The new configuration option defaults to 1 if not specified in the
appender options and is passed to the FileAppender struct during
initialization.
```
