devfaroff/Filestore ? reverse-engineered prompt

Build me a Telegram file store bot that runs on Vercel and saves uploaded files and messages in a private Telegram storage channel, with MongoDB for metadata. I want people to be able to upload files, photos, videos, and text in a batch, then get a secure share link with a random token. The bot should support a start menu with inline buttons, file search, batch forwarding from existing channels, and special post flows where I can send a thumbnail, title, and multiple videos, then create one share link for them.

Please include password protected links, Telegram Stars paid access, force subscribe, auto delete after a time limit, and a settings panel for the bot owner. I also want a clone system so other people can connect their own bot token and manage their own uploads and settings. Use permanent links on my Vercel domain that redirect to the active bot. If you need to check current Telegram or Vercel docs while building, go ahead.
