Release v4.73.2

Changed

• expand-layout refuses to propose a layout that would change the authored order of modules, features or slices. It now takes that order from the same root the compiler's timeline check uses, so an import-less application.play beside a single importing file no longer leads to path order. When there is no root to take the order from, the proposal's review text says that path order was used. (#412)

Fixed

• Merging a folder model back into one document no longer drops comments written on authorize statements. (#412)
