feat(json): validate JSON schema via the jsonschema crate

Replace the todo!() json_schema::Validator stub with the jsonschema crate.

Errors are surfaced as 'property : message'; the message wording follows the
jsonschema crate and is *not* justinrainbow-compatible.

Port the ComposerSchemaTest and JsonFileTest schema cases to the new wording
(noted per test).

+//! WORDING NOTE: the upstream PHP tests assert justinrainbow's structured
+//! `{property, message, constraint}` error arrays (e.g. "Does not match the regex pattern …",
+//! "Array value found, but a string is required", "Does not have a value in the enumeration …").
+//! Shirabe validates with the `jsonschema` crate, whose message wording differs. These ports
+//! therefore assert the equivalent `property : message` strings using jsonschema's wording.
+//! Only the wording changed — the validation behavior (which inputs are valid/invalid and on
+//! which property) is identical to upstream.
