Automated by the revendor-canonical-schema workflow
(scripts/revendor-canonical-schema.sh).

The canonical block-manifest schema published at
https://civitai.com/schemas/app-block/v1.json changed, so the CLI's
go:embedded mirror (schema/app-block.manifest.schema.json) drifted
and check-canonical-schema would go red. This PR re-vendors the
embedded copy from the canonical.

Validated in the job before opening: the re-vendored schema compiles
under the CLI's jsonschema engine and the bundled example manifests
still validate against it (go test ./...).

Reviewer heads-up: this bot only re-vendors the schema bytes
and records which author-facing pattern glosses that leaves owed. If
the canonical change added a field with author-facing semantics
(e.g. a new manifest key), consider whether internal/validate/ (the
Go semantic checks / friendly messages) should track it too — that
part is a deliberate human call.

⚠️ 1 schema pattern(s) now have no author-facing gloss (^[a-z][a-z0-9_]{0,31}$). An author who trips one gets the bare regex back — correct but terse. The debt is recorded in internal/validate/pattern_gloss_owed.json; clear it by writing the gloss in internal/validate/pattern.go. This PR is still safe to merge as-is.

Superseded by #868. This branch's schema is byte-identical to current main (its additions already landed via #865), and it predates the canonical's cross-app storage imports (civitai web v5.1.425): storage.imports, collection exportable, and the apps:storage:import scope. #868 re-vendors from the live canonical with scripts/revendor-canonical-schema.sh and adds a fork-manifest test.
