kalanakt/All-Url-Uploader — reverse-engineered prompt

Build me a Telegram bot that lets people send a direct download link and get the file uploaded back into Telegram automatically. It should handle normal file URLs, links with a custom filename, and links that also include a username and password. I also want it to support popular media links like YouTube, with quick audio and quick video options, plus format selection when that source supports it.

Please make the bot send the result back using the right media type with basic metadata, and let each user save or delete their own custom thumbnail with commands like start, help, about, thumb, and delthumb. It should have simple config through an env file for the bot token, owner ID, allowed users, download folder, proxy, chunk size, and timeout.

Make it clean and runnable locally, and also easy to run in Docker if possible. If anything is unclear, look up the current docs online and wire it up so it actually works end to end.
