JSON Schema corpus

The runner executes the complete local Draft 2020-12 and Draft 7 groups from the official JSON-Schema-Test-Suite revision pinned in corpus.json. Draft 7 schemas receive the canonical dialect declaration before validation because an absent $schema intentionally defaults to 2020-12 in the product.

The runner never starts the suite's HTTP server and never resolves external documents. Allowlisted cases are limited to schemas that require those unavailable external documents; unexpected failures and stale entries fail the run.

Run it against an exact checkout:

bun tests/json-schema/run.ts /path/to/JSON-Schema-Test-Suite

Every external-document case must have a file/group/test entry and reason in corpus.json.
