Rolldown cli options does not work when values are chained by dot operator.

For example if i do rolldown --config ./rolldown.config.js --generated-code.profiler-names it shows as invalid value

What is expected?

The cli option should be accepted and not throw an an error.

What is actually happening?

Th bug is because cac only converts the top level option to camel case and not the nested values as we can see here

it actually works when i put a camelCase after the dot operator
