Setting to modify character limits on comments

Can we have a simple setting to set up the character limits on comments?

https://meta.answer.dev/questions/D1U23/is-it-possible-to-configure-the-comment-length-limit-witch-is-currently-600-characters

It's super annoying for users to split messages in two

Start by reviewing the linked meta.answer.dev discussion to understand the requested configurable limits and the current 600-character behavior. Then locate the comment validation and settings entry points in the repository. Done means users can configure the comment limit and comments consistently enforce that setting.
