add example of top-level key in settings.json

[ornwilson]

It would be helpful for some to put the exact settings.json notation example in the readme also.

From a certain post somewhere:

`You can either replace the existing Claude defaults, or add on to it with the "append" mode. To add these verbs, just drop this in your ~/.claude/settings.json:

{
"spinnerVerbs": {
"mode": "append",
"verbs": ["Second-breakfasting", "Silly-walking", "Great-scotting"]
}
}
