TRACE / CAT Reporting Lint

FINRA Rule 6730 TRACE trade-report timeliness against a caller-declared trading calendar and hours window, plus a CAT equity/option order-event structural format-lint over a representative subset of required fields. There is no built-in market calendar — weekend days and holidays are supplied by the caller. Honestly scoped: not a full implementation of the CAT Reporting Technical Specification.
