chore(config): add scope definitions to config.yml

- Introduce scope definitions for conventional commits
- Document descriptions for cli, config, domain, services, shared, and tests

This commit adds a new configuration file that defines the scopes used
for conventional commits. It helps maintain consistency and clarity
across commit messages by explicitly listing available scopes and their
descriptions.
