- New _Clarification sentinel and _resolve_series_folder() helper —
the three TV use cases now share one matching/clarification path
instead of triplicating the same if/elif/else block.
- New _ResolvedDestinationBase carrying status/question/options/error/
message plus a _base_dict() helper; the four concrete DTOs only
declare their own ok-state fields and a slim to_dict().
- No behaviour change: same outputs for ok/needs_clarification/error
cases (verified by import + DTO smoke tests).
