Anti-corruption boundary tightened on the TMDB adapter: * TmdbMovieInfo / TmdbShowInfo now carry domain VOs (TmdbId, ImdbId, MovieTitle, ReleaseYear, ShowStatus) instead of raw scalars — validation happens at the boundary, not three layers later. * ShowStatus enum added (domain/tv_shows/value_objects) with a from_tmdb() mapper that falls back to UNKNOWN + logs a warning on unrecognized values. TVShow.status is now ShowStatus, not str. * MovieTitle cap raised from 100 to 150 chars. * MediaResult / ExternalIds dropped. Replaced by per-media search DTOs: TmdbMovieSearchResult and TmdbShowSearchResult. Neither carries imdb_id — search no longer enriches with external_ids (callers needing imdb_id follow up with get_movie_info / get_tv_show_info on the chosen tmdb_id). * TMDBClient: search_multi / search_media / _parse_result removed. search_movies (/search/movie) and search_shows (/search/tv) added, each parsing hits into VO-typed DTOs. * SearchMovieUseCase returns a list of MovieHit (flattened to primitives for the agent). New symmetric SearchShowUseCase + ShowHit / SearchShowResponse DTOs. * agent/tools/api.py: find_media_imdb_id → search_movies + search_shows wrappers. * FileEntry moved from domain/shared/ports/filesystem_scanner.py to domain/shared/file_entry.py (it's a DTO, not a Protocol); size_kb (float) → size (int bytes). Scanner and SubtitleIdentifier updated. Tests: 79/79 pass on tests/infrastructure/api/ + tests/application/test_search_movie.py + tests/application/test_search_show.py.
