Release v3.20.0

Changed

• A generated application targets the current package set instead of one roughly thirteen minor versions behind on Arc and three majors behind on the Chronicle kernel image. The kernel image tracks the Chronicle client the metapackage brings, not the newest tag. (#100)

Fixed

• A keyed lookup over a raw key declares its parameter as the event source id rather than the string it is stored as, so the incoming value is validated instead of being converted inside the method after validation has run.
• Generated command specifications dispose the scenario they own, so a generated application builds where analysis is treated as errors.
• Generated specifications no longer declare the globalization namespace unless something in the file uses it.
• A generated read model states its key, so an instance is self-identifying rather than leaving the key implicit in its event source.
