ilkerccom/btcpuzzle ? reverse-engineered prompt

Build me a desktop command line client for btcpuzzle.info that can join their puzzle pool, scan for Bitcoin puzzle ranges, and report progress back to the pool.

I want it to run on a GPU, let me set the target puzzle number, my user token, worker name, and optional custom scan range, then automatically handle notifications when a key is found. Please include support for saving a found key securely with an RSA public key, plus options for sending the encrypted result through a webhook or Telegram instead of storing it. Make it easy to configure from a simple config file and also accept command line arguments for the main settings.

If there are any current API details or setup steps that matter, look them up online if you need to. Also make sure it works well in Docker and can be built on Linux, with a sensible default config and clear error messages when something is missing.
