Modified the 'loadConfig' method to support '.cjs' and '.mjs' config files. Also, a 'changeExtension' function is added to helpers/path.ts to manipulate file extensions. An error will be thrown if a specified user config file is not found. The application defaults to the default config file if no user config file is provided.
This commit introduces configuration and path management functionality in the CLI by adding the helper functions to load and validate configuration. It also provides the logic to retrieve available components from a given registry. Additionally, it exposes these functionalities in public API.
