3.1.1

• chore: declare Node.js 22 as the floor
• feat(packet): Extended DNS Errors (RFC 8914) — Packet.EDE INFO-CODEs, an EDE
  EDNS option codec, and Packet.createErrorResponseFromRequest
• feat(packet): Packet.RCODE completed from the IANA registry — 6-11 and 16-23
• feat(ts): Packet.RCODE was missing from the type declarations entirely
• feat(packet): Packet.parse stops at a failure that leaves the reader misaligned
• feat(packet): RDLENGTH bounds every rdata decoder, so a malformed record no longer cascades (RFC 1035 §4.1.3)
• feat(packet): Packet.typeName, Packet.TYPE_NAME, Packet.EDNS_OPTION_NAME
• feat(client/udp): a query timeout names the last dropped response and why
• feat(index): resolve() uses Promise.any, so one dead NS no longer fails all
• fix(packet): parse throws Packet.DecodeError for a message with no usable header
• fix(packet): parse no longer swallows per-record decode failures, reports on packet.errors
• fix(packet): encoding a record or question whose TYPE/CLASS is not a 16-bit int throws
• fix(packet): encoding an A/AAAA record with an invalid address throws, was 0.0.0.0
• fix(packet): RRSIG was unreachable — Packet.TYPE.RRSIG (46) was missing
• fix(packet): RRSIG timestamps mixed the local-time year with UTC fields
• fix(packet): RRSIG retains raw rdata so re-serializing keeps the signature
• fix(packet): EDNS skipped unknown options by bits instead of octets
• fix(packet): length validation for A, AAAA, CAA, DNSKEY, RRSIG and ECS rdata
• fix(packet): Packet.readStream rejects a truncated message
• fix: DNS option timeout is ms and now reaches the client (default 3000)
• fix(index): resolveA(domain, clientIp) never sent the ECS option
• fix(client/doh): a non-200 response rejected and then resolved
• fix(packet): drop the Array.prototype.flatMap polyfill for Node 10
