Give the terminal's classpath an nREPL, and hand recipes their arguments

`just nrepl` is `tui` with an nREPL on the end instead of a `-main`, so a
component can be redefined and re-mounted in the session that is on screen
rather than rebuilt.

And the thing that made it worth finding: a `#!` recipe is interpolated, not
handed argv, so `"$@"` was empty in every recipe here — `just tui --headless`
opened the terminal instead.
