Validate a document against a remote JSON Schema API

Fetches a JSON Schema by URL (any draft Ajv supports) and validates a supplied document against it, returning a valid flag, an error count, and per-error details (instance path, failing keyword, message, schema path). The MORE: the schema is resolved remotely so an agent supplies only the data and a schema URL — no need to embed or maintain the schema. Answers 'does my JSON conform to this published schema', 'validate this config against its official schema', 'why is my document invalid'.
