handle envelop on grpc GetNetworkMap

On iOS the tunnel reconfiguration (setTunnelNetworkSettings) was driven
from three independent Go paths without serialization: route prefix
updates via the route notifier's own delivery loop, interface IP/IPv6
set synchronously from the engine start goroutine, and DNS config
applied from the DNS apply chain through a separate Swift object. The
three sources mutated the shared Swift settings-manager state
concurrently and triggered overlapping updateTunnel() calls, losing or
half-applying route and DNS settings.

Introduce client/internal/tunnelnotifier: a single notifier that
implements both listener.NetworkChangeListener and dns.IosDnsManager,
queues all four callbacks (OnNetworkChanged, SetInterfaceIP,
SetInterfaceIPv6, ApplyDns) in one FIFO and delivers them one-by-one
from a single goroutine, so calls into Swift never overlap and arrive in
order. RunOniOS wraps the two Swift objects into the notifier and closes
it after the run loop exits.

The route notifier keeps its prefix dedup but delegates delivery to the
shared notifier instead of maintaining its own queue and loop; the dedup
check and the enqueue stay under one mutex so queue order matches
state-update order. Setting the interface IP becomes asynchronous, which
is safe: on iOS wgInterface.Create() only uses the TunFd, and the FIFO
preserves the IP -> routes/DNS relative order.

The package is build-tag free so the unit tests run on any platform
under -race. Android is unaffected: it receives all settings atomically
in one configureInterface call and serializes TUN rebuilds on a single
handler thread.

## Summary by CodeRabbit

* **New Features**
* Improved iOS tunnel networking by coordinating network, interface,
route, and DNS updates through a unified notifier.
* Updated iOS behavior so route/prefix changes are applied immediately
instead of via queued/background delivery.

* **Bug Fixes**
* Improved reliability by ensuring network and DNS-related callbacks are
invoked in order without overlap.
* Ensured pending updates are drained and handled correctly during
shutdown.

* **Tests**
* Added coverage for FIFO ordering, non-overlapping callback execution,
interleaved DNS/route updates, and graceful shutdown behavior.

+- The model allowlist is enforced in TWO places. `CheckLLMPolicyLimits`
+  is authoritative: it resolves the policy that governs this
+  (provider, caller-groups) and denies (`deny_code = llm_policy.model_blocked`)
+  when no applicable policy permits the model — so an allowlist scoped to
+  one group/provider never leaks to another, and an un-guardrailed policy
+  is genuinely unrestricted. `llm_guardrail` is a per-provider fail-closed
+  backstop: it only carries an allowlist for a provider every authorising
+  policy restricts, and blocks unknown/undetermined models even when
+  management is unreachable. Because that backstop allowlist is the UNION
+  of every restricting policy's models, per-group narrowing lives only in
+  the authoritative check: during a `CheckLLMPolicyLimits` outage
+  `llm_limit_check` fails open, so a caller can reach any model in the
+  provider's union — a group scoped to model A could reach model B if
+  another group restricts the same provider to B. This is the documented
+  fail-open trade-off; a future flag may switch it to fail-closed.
 - SSE streaming requires special handling on the response side; the
   parser must handle partial chunks without buffering the whole
   stream. See [`modules/32-proxy-llm-parsers.md`](modules/32-proxy-llm-parsers.md).
