0.6.0 --- follow openkal 0.12 (#12)

No behaviour changes. The specification's 0.12 additions are prose: clause 11
entry 9 names what handles-do-not-cross costs a caller composing job control,
and the two file-creating operations point at entry 6.

The bump exists because a version requirement here is exact --- nothing floats
up --- so a specification release moves the whole graph or nothing resolves.
