Module transport 

Phantom Protocol transport internals.

The protocol layer beneath the public crate::api surface. PhantomUDP — a QUIC-class reliable transport over raw UDP — is the production transport; TCP / WebSocket / WASI / Embedded / TLS-mimicry byte-pipes also plug in via SessionTransport. Key properties:

• Multi-streaming (independent streams, no head-of-line blocking)
• 0-RTT connection establishment (resumption + early-data)
• Seamless single-path connection migration (session survives IP changes)
• Adaptive fallback tiers (Turbo → Reliable → Stealth, see fallback)

NOTE: multipath bandwidth aggregation / multi-homing was deliberately rejected — migration moves one active path at a time, it does not bond paths. The scheduler module is consequently vestigial.
