Server now assigns each connected client an IP from a configurable pool and
maintains a client_ip -> AuraConnection map so packets read from the shared
TUN are dispatched to the right client (and each client's recv loop writes
back to the TUN). Removes v1's "single shared TUN, no NAT/pool" limitation;
turns the server into a proper multi-client VPN concentrator (paired with the
already-landed UDP multi-client demux).
- aura_cli::pool: IpPool + PoolStrategy {StaticOnly, DynamicOnly,
StaticOrDynamic}; reserves network/broadcast/server-own IP; 15 tests.
- aura_cli::server_router: ServerRouter + ServerRoutes (Arc<RwLock<HashMap>>);
central TUN read loop dispatching by dst_ip; spawn_inbound_forwarder per
conn auto-unregisters and releases the IP on disconnect; 4 tests via
MockTun + MockConn.
- aura_cli::config: [server.pool] {cidr, strategy, static} added with
serde(default); legacy configs (only [tunnel] pool_cidr) fall back to a
DynamicOnly pool (backward compatible, tested).
- aura_cli::server: accept loop now: pool.assign(peer_id) -> register ->
spawn_inbound_forwarder; rejected static_only mismatches dropped+logged.
- config/server.toml.example: documented [server.pool] section.
Workspace: 141 tests passed (+24), clippy -D warnings clean, fmt clean. No
new workspace deps (async-trait added to cli dev-deps for mock traits in tests).

aura-cli: clap command tree (pki init/issue-server/issue-client/revoke/list,
server, client, route add/list/remove, status, bench-crypto); TOML config with
~ expansion and split-tunnel rules -> RouteTable; JSON-over-Unix-socket admin
IPC; server/client data paths wiring transport + tunnel (TUN run needs root).
config/{server,client}.toml.example. 15 tests (pki roundtrip, config parse,
admin-socket roundtrip, loopback connection). Verified the real binary: --help,
bench-crypto, and a full CA->server->client cert workflow.

- 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
