Go Formatter

Following Go standards, this tool uses tabs for indentation, which is the official preference of the Go development team and the gofmt utility.

Yes, since semicolons are mostly optional in Go and handled by the lexer, the formatter cleans up unnecessary semicolons to keep the code idiomatic.

It is inspired by gofmt. It helps developers who don't have the Go toolchain installed locally to quickly format their snippets for sharing or review.
