Module ids 

Newtype wrappers for the protocol’s identifier fields (RFC §6.1.1).

Identifiers are categorised into two flavours:

• Prefixed ULIDs for runtime-minted identifiers. The on-the-wire form is <prefix>_<ULID>; the prefix is asserted on parse. Mixing a SessionId with a MessageId is a compile error.
• Free-form opaque strings for ids whose format is determined by the environment: TraceId and SpanId (per OpenTelemetry / Datadog / Honeycomb conventions, §17.1) and IdempotencyKey (client-supplied logical intent key, §6.4).

Structs
