Build me a full featured social media app where people can sign up, log in, and manage their profile, then follow other users, create image posts with captions, like and comment on posts, save posts, and report content if needed. I want a modern feed with infinite scrolling, user search, profile pages, followers and following lists, and a place to see saved posts.

It should also have real time chat between users with typing status, online presence, delivery and read receipts, message replies, editing, deleting, and the ability to share posts in chat. Add real time notifications for follows, likes, and comments, plus unread badges and a history view. Use image uploads for profile photos and posts, and make sure everything is secure with proper auth, session logout, password change, validation, and rate limiting. If you need to look up current docs online, go ahead.
