Replace unmaintained gohxs/readline with latest chzyer/readline

The Go library `gohxs/readline` has no commits for past 8 years. It was originally forked from `chzyer/readline`, which continues to be maintained, so switch back to it to ensure continued maintenance and updates. This change necessitated adapting the output filtering mechanism due to API incompatibilities that manifested as errors: rline/rline.go:128:16: l.Inst.Config.Output undefined (type *readline.Config has no field or method Output) rline/rline.go:130:7: cfg.FuncFilterOutput undefined (type *readline.Config has no field or method FuncFilterOutput) Specifically, the `readline.Config` no longer provides direct output fields or filter functions. To address this, implement a `filterWriter` to wrap the standard output stream, ensuring existing output filtering functionality is preserved. Closes: #528
