Subject: [PATCH] feat(cli): add configuration and path management
 functionality

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.
