fix(keys): snippets survive being pasted into real zsh

The copyable text opened with a "# hint" line — but default interactive
zsh has interactivecomments off, so the line was parsed as a command, and
the "!" inside «(перезапишет!)» fired history expansion: pasting the
OpenCode snippet died with "zsh: event not found: )" before doing
anything. Hints now live in the UI above the snippet; the clipboard gets
commands only. Verified by piping the actual rendered snippet through an
interactive zsh: the config file lands intact.
