0.9.2

ACCEPTANCE-0.1b.md was written while CI was still red and said so: "no CI run
exists for this milestone yet". The 0.9.1 fix made the matrix green on all
four platforms, which made that line wrong an hour after it was written. It now
says what happened, including that the Linux leg had been red since 0.7.5 —
scope §19's "sem verde nos quatro, marco desktop não fecha" is satisfied by
that run, not by a document claiming it.
