Note / 说明

Fix subscriber-only posts (TweetPreviewDisplay) not appearing in /twitter/user/:id feed.

The X API returns subscriber-only posts with __typename: "TweetPreviewDisplay", which has a different structure from regular Tweet objects. The parser silently dropped these entries because the type was not handled.

Added a handler in both web-api/utils.ts and mobile-api/api.ts. The check must occur before the tweet = tweet.tweet reassignment. Preview text is included in the feed with a 🔒 prefix.
