M4elstr0m/gophoner ? reverse-engineered prompt

Build me a Go tool called gophoner that lets me check whether a phone number seems to be registered on a few popular services, one number at a time. I want both a normal command line mode for quick use and an interactive terminal mode that guides me through it. The checks should run at the same time so it feels fast, and the output should clearly show which services matched and which did not.

Please make it cross platform for Windows, macOS, and Linux, with a clean terminal experience, progress feedback, and a JSON option for piping results into other tools. It should also be careful about privacy, so phone numbers should not be written to logs unless debug mode is on, and there should be a way to disable logging and update checks. If you need to look up current docs online, go ahead.
