refactor: create three distinct Rails classes, InputRails, OutputRails, and DialogRails #1151
Description
based on config, LLMRails (composer) picks or assembles the right pieces. Users can still explicitly pick one mode, or get “everything” under one roof.
we need an abstract base, concrete single purpose implementations, and a small factory/composite to glue them under LLMRails umberella for example.
- introducing BaseRails
- extracting three single responsibility implementations
- InputRails
- OutputRails
- DialogRails
