Use json:encode/1 and json:decode/1 directly instead of the configurable json_lib approach via nova:get_env. The json_lib config option was removed from Nova. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Update pre_request/post_request to 4-arity callbacks matching the current nova_plugin behaviour. Update plugin_info to return a map instead of a tuple. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Wrap validation errors in RFC 9457 Problem Details envelope (type, title, status, detail, errors) - Default status code changed from 400 to 422 (configurable via status_code option for backwards compatibility) - Set Content-Type to application/problem+json on error responses - Add JSON Pointer (RFC 6901) paths for field locations - Normalize error keys to path, message, type, actual_value, expected - Handle all Jesse error types (schema_invalid, data_error, schema_error) instead of only data_invalid - Guard file:read_file in validate_json to return clean error on missing schema files instead of crashing - Add group_by_field option to group errors by field path for form-friendly consumption - Bump version to 0.3.0 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add 56 EUnit tests covering RFC 9457 error rendering, JSON pointer generation, format messages, pre_request/post_request callbacks, and validate_json with jesse integration. Fix bug where binary schema keys passed to jesse:validate would crash with function_clause since jesse_database:load/1 only accepts lists. Add ensure_list/1 helper to convert binary keys. Update nova dep to 0.13.7, add meck test dep, xref_ignores for plugin callbacks, rebar3_audit and rebar3_sbom plugins.
