Install scripts to ~/.config/ollie/scripts/ (not ~/bin/) so they are
served via the 9p mount without PATH changes. Add thin wrappers oq-q
(s/q, foreground one-shot) and oq-schedule (s/sched, background with
b/ path output). Switch osh and oq from OLLIE_9MOUNT to OLLIE.
Update mkfile, docs, and submodule pointer.
