Kqzz/MCsniperGO — reverse-engineered prompt

Build me a Go command line tool like MCsniperGO that can load Minecraft accounts from two text files, one for accounts without usernames and one for accounts that already have usernames, plus a proxies file. I want it to accept either email and password pairs or bearer tokens, then ask me for a target username and a unix claim range, and start sending claim attempts as fast as possible through the proxies while showing clear logs and status codes for each request.

Please keep the account file format simple, show how many accounts were loaded, and make it obvious when a token is expired or when an account is unauthorized. I also want the logs to explain common responses like failed claim, unauthorized, and too many requests. Include a basic README with setup and usage, including how to run it and how to get the claim range from sites like NameMC or 3name.

Also, keep the warning that this kind of username claiming is no longer really effective because of rate limits, so treat it as an archival or educational recreation. Look up current docs online if you need to.
