Is it possible to add custom rules?

Depending on the usage, we might want to add our rules, or modify existing rules by changing the type etc.
Is it possible to do with openapi-diff?
Thanks!

The issue does not name any files, tests, or entry points. Start by locating how openapi-diff defines and applies its existing rules, then determine whether custom rules or rule-type overrides have a supported configuration path. Done would require a documented, agreed approach for adding or modifying rules.
