A structured-data shell in Gleam, inspired by Nushell

Add whyport, now, input, from jwt, and dotted get paths. master

Port listeners (`whyport`), epoch time (`now`), multi-line paste (`input`), JWT parse-only decode (`from jwt`), and `get a.b` cell paths make common inspection workflows usable without leaving the shell. Document the new commands in the README examples and language sketch.
