Closes: WORLD-1084 & WORLD-1078 & WORLD-1045

## Overview

Fix find world.toml recursively on parent dir

## Brief Changelog

- load config and get root dir
- change hardcoded chdir using rootdir
- fix return error when file not exist

## Testing and Verifying

Manually verified by running `world cardinal dev`
