Summary

Lack of default config. Time taken to run commitlm init (grab API keys, select model etc) on every project git directory.

Proposed solution

1. Add a new command, commit default-init to setup initialization and save JSON file at user root directory ($ ~).
2. After initialization is complete in commitlm init, offer the user to save as default.

Test plan

1. Auto initialization when run commitlm init, after default config is setup.
2. [OPTIONAL] run git c without requiring commitlm init project dir.

I'd work on this also.
