FeedId is now the type of Feed.id and of every single-feed method on FeedRepository; callers wrap raw strings via FeedId.fromTrusted at the repository boundary. String-medium operations (URLs, logs, JSON, list registry, email keys) stay string. Drop the redundant generateFeedId wrapper in favour of FeedId.generate.
