feat: enrich RSS items without IDs via TMDB title search

Items from RSS feeds that have no media ID (tmdb/imdb/tvdb) are now
enriched automatically using TMDB's search API. The release name is
parsed to extract a clean title and year, then searched against TMDB
to retrieve the TMDB ID before validation.

- Add media/tmdb package with SearchMovies, SearchShows, and
  ExtractTitleAndYear (parses torrent release names)
- Add EnrichFeedItemWithTmdbId to media.Client, called in rss/process.go
  before the ID validation switch
- Add --run-now flag to nabarr run to trigger all feeds immediately
- Wire media.Client through rss.Client and rssJob
- Merge feature/add-tag-option (tag support for Sonarr/Radarr)
