Class RestOperationAbstract

RestOperation is the REST protocol layer shared by every REST-style provider.

It is the REST counterpart of the shared GraphQLOperation base: both extend the BaseOperation transport plumbing, but this class shapes plain HTTP requests instead of GraphQL documents — path-based URLs with query strings, JSON bodies, and verbatim response bodies (no envelope unwrapping). Failures surface as AniLinkRestError via the shared pipeline's error normalization.

Concrete operations declare their endpoint path, parameter interface, and a thin method that calls execute.
