The family envelope: every --json answer in the exit and JSON contract spec-spine speaks

Amends 006 sections 3.3 and 3.4. Every --json answer this product writes becomes the envelope spec-spine has written since 0.26.0 (its spec 132 section 3.4): schemaVersion, tool, verb, outcome, exitCode, summary, then report for exit 0 or 1 and error for 2, 3 or 4, where error.kind is one of the family's ten tokens. No exit number moves. A usage error under --json is an envelope on stdout. The replacement of 002 section 3.23's check translation, which #118 proposed for the same change, is left to the spec-spine 0.28.0 adoption, which changes the producer answer it would read. Replaces the historical proposal from #118 with the amendment that the current model requires (001 section 5).
