RFC 8460 SMTP TLS Reporting (TLSRPT) — _smtp._tls TXT record parser, RFC 8460 §4 JSON report data model, FailureType enum (14 result-type values from §4.3), and a builder that takes per-connection event facts and produces an owned daily report ready to serialize + sign + submit. Pure: no SMTP / HTTPS / gzip in-crate. Pairs with mailrs-mta-sts.
