Interface ManifestMismatch

One disagreement between package.json and what src declares.

kind says which contribution point, direction which side is missing something — or drift, when both have the entry and disagree about it — and id the command, setting key or view it concerns. summary says the same thing to a person; paste is the JSON that would settle it, present when the fix is mechanical and absent when only a person can supply it (a view needs a container; a command needs a title).
