0.5.0 --- follow openkal 0.11

A repin. openkal 0.11 collapses the three spawn declarations into one and makes
the unit a program belongs to a resource the caller holds; nothing here provides an interface those declarations belong to.

⚠️ A version requirement in this ecosystem is exact and does not float up, and
`openkal' is the shared dependency of the whole graph --- a package left behind
does not keep its own older contract, it makes the graph irreconcilable.
