Can you provide some more details about the situation you are encountering and the problem you are facing? Some more context will help me determine if this is the best approach or if there is perhaps a better solution to your issue.

@stevearc When there is a Taskfile in a subdirectory, tasks can only be executed within that subdirectory.

Currently, if you open a Taskfile in a subdirectory and run OverseerRun, the tasks that can be executed in that subdirectory are listed. However, when you actually execute a task, it runs in the current directory (the parent directory), fails to find the task, and execution fails.

Therefore, this pull request aims to enable the correct execution of tasks in the subdirectory by running the tasks in the directory of the opened file.

Makes sense, thanks for the PR!
