Implement full two-exchange NTP client state machine (RFC 5905 §8).
First exchange stores offset/RTT, second averages both for improved
accuracy. Client places T1 in TransmitTime per RFC 5905 §8; server
echoes it as OriginTime in the response.
Add NTP extension field codec (RFC 7822) with NextExtField iterator
and AppendExtField builder. Add NTS extension type constants from
RFC 8915.
Add NTP Server (StackNode) that receives client requests via Demux
and builds server responses via Encapsulate with configurable
stratum, precision, reference ID, and pending request queue.
Add Frame accessor methods: RawData(), ExtensionFields(),
ValidateSize(), and Timestamp.Uint64().
Add ntp-client and ntp-server example programs with
CalculateSystemPrecision, retry limits, and backoff.
Use internal.LogAttrs pattern for non-allocating structured logging
in the client, matching the tcp/debug.go convention.
