feat(crypto,cli,transport): daily protocol-mask rotation at 05:00 MSK

Both server and client deterministically rotate the on-wire obfuscation mask
(SNI, HTTP Host/User-Agent/Server headers, UDP padding profile) at 05:00 Moscow
time (02:00 UTC) every day, derived from the CA fingerprint + UTC date — no
network coordination needed.

- aura-crypto::masks: MaskSet + 4 palettes (16 SNI, 10 UA, 5 Server, 4 padding
  profiles); derive_mask_for_msk_date via HKDF-SHA256(salt="aura-mask-v1-salt",
  ikm=ca_fp||"YYYY-MM-DD", info="aura-mask-v1"); ca_fingerprint with built-in
  base64 PEM decode (no new deps).
- aura-cli::masks: MaskRotator (Arc<RwLock<MaskSet>>) + Hinnant's civil_from_days
  for manual UTC date math; scheduler picks next 02:00 UTC strictly (avoids
  busy-loop at boundary); spawned at startup in server::run/client::run.
- aura-transport: PADDING_PROFILES + next_bucket_for_profile (profile 0 byte-for-
  byte equals legacy pad_to_https_size); TcpOpts gains user_agent/server_header;
  UdpOpts gains padding_profile; MultiServer holds Arc<UdpServer>/Arc<TcpServer>
  with set_udp_opts/set_tcp_opts so rotation propagates without restart.
- Backward-compatible: defaults preserve previous behavior; existing 97 tests
  unchanged. 17 new tests (derive determinism + date variation, civil-from-days
  known points incl. 1970-01-01/2000-02-29/2024->2025, next-rotation boundary,
  msk_today offset, profile equivalence, base64 round-trip, full mask-driven
  UDP loopback). Total: 114 passed, clippy/fmt clean. No new workspace deps.

feat(transport,tunnel): implement Wave 3 — QUIC transport + split-tunnel router

aura-transport: quinn 0.11 endpoint with HTTP/3 mimicry (ALPN h3/h3-29,
Chrome-like transport params), outer-TLS accept-any (real auth is the inner
Aura handshake), packet padding to HTTPS sizes; AuraServer/AuraClient drive the
proto handshake over a QUIC bidi stream; AuraConnection impls
aura_proto::PacketConnection (full-duplex via Session::split + per-half mutex).
14 tests incl. a real-QUIC loopback end-to-end (crypto+pki+proto+transport).

aura-tunnel: RouteTable (longest-prefix split-tunnel classify), AuraDns
(hickory) host-route registration, AuraRouter over a PacketIo TUN seam +
Arc<dyn PacketConnection>, AuraTun (tun 0.8 unix; wintun cfg-gated Windows).
10 tests (route classify/priority, dst-IP parse, mock router). send_direct is a
v1 stub. Whole workspace: tests green, clippy clean.
