+who and +where commands. Demonstrates the standard two-object shape:
ww_globalcarries the$commandpatterns and@parents to the function object so command code can call shared functions viau().ww_functionsisno_commandand holds only callable attributes.
Both cross-object references use the ~internal ref form
(parent: ~ww_functions, u(~ww_functions/WW_FN_HEADER,...)), which the
install engine substitutes with the real dbref at apply time.
The WW_ convention prefix marks this package's attribute namespace.
