EXTENDED_KEYWORDS
Additional draft 2019-09 / 2020-12 applicator keywords that the built-in
vocabulary intentionally does NOT traverse by default (to preserve existing
observable behaviour). Pass via options.additionalKeywords to opt in:
new JsonSchemaScanner({ options: { additionalKeywords: EXTENDED_KEYWORDS } });
dependencies (draft-07, whose values may be either a schema or a string[])
is deliberately excluded because its array form is not a subschema.
