* fix: Add recursive file search to stela configuration
Introduced a recursive file search in stela configuration's `get_settings` method. The change added a helper method `recurse_find_file`, which looks up for configuration files from the current directory up to the root one. This change helps to locate the 'pyproject.toml' and '.stela' configuration files, improving application stability and user experience.
