Make phan stricter about null types by setting null_casts_as_any_type to
false (the default in mediawiki-phan-config)
Remaining false positive issues are suppressed.
The suppression and the setting change can only be done together

Make Command extend Shellbox's UnboxedCommand. Only a few MediaWiki-

Also add BoxedCommand abstraction and Shellbox client.
The Result alias didn't actually work, I just had to change the return
type hint.
