Define the async PacketConnection trait (send_packet/recv_packet over &self)
that aura-tunnel's router consumes and the QUIC connection will implement.
Committed before Wave 3 so the transport and tunnel agents build against a
stable cross-crate contract from isolated worktrees.

Compose Session from SessionSender (writer + outbound AEAD/seq) and
SessionReceiver (reader + inbound AEAD + replay window); split() hands back
the two halves so a VPN data path can run concurrent read/write tasks
(recv_frame is not cancellation-safe, so select! on one &mut Session is unsafe).
send_frame/recv_frame/peer_id/into_inner unchanged; 13 tests still green.

- 6-crate Cargo workspace, dependency tree frozen (cargo check green in ~1m)
- ml-kem 0.3 (FIPS 203) replaces spec's pqcrypto-kyber for ML-KEM-768
- fix invalid target-gated workspace.dependencies: Windows deps (wintun/windows)
declared untargeted, cfg-gated per-crate in aura-tunnel
- version bumps vs spec: tun 0.8, rcgen 0.14, wintun 0.5
- stub lib/main per crate; real implementations land wave by wave
