[M3] mxaccess-nmx: NmxClient — 9 raw INmxService2 opnums (stream B)

Browse Source 
Lands M3 stream B raw opnum surface: an async NmxClient over the
mxaccess-rpc transport that dispatches all 9 INmxService2 procedures
(GetPartnerVersion, RegisterEngine2 + WithoutCallback, UnregisterEngine,
Connect, AddSubscriberEngine, RemoveSubscriberEngine,
SetHeartbeatSendInterval, TransferData) plus a NonZeroHresult error
variant that mirrors ThrowIfFailed (cs:563-574).

New
- crates/mxaccess-nmx/src/client.rs (~580 LoC, 8 tests including 5
  real-socket tokio tests against a hand-rolled DCE/RPC server) — port
  of the raw opnum surface from ManagedNmxService2Client.cs.
- NmxClient::connect builds the NTLM-packet-integrity bind path; for
  tests, NmxClient::from_bound_transport accepts a transport bound any
  way the caller likes (the test server doesn't validate signatures).
- fresh_orpc_this generates a per-call Cid via rand::random(), mirroring
  the .NET reference's Guid.NewGuid() at every call site.
- NmxClientError::NonZeroHresult unifies the .NET reference's
  Marshal.ThrowExceptionForHR + InvalidOperationException branches so
  callers see one typed surface for "transport-OK + LMX rejected".

Cargo.toml: added tokio, tracing, thiserror, rand to mxaccess-nmx.

Two layers of the .NET reference are deliberately out of scope this
iteration; both logged as new followups in design/followups.md:

- F12 (P1): the auto-resolving Create() factory, which needs windows-rs
  COM activation (gated by F6) + ComObjRefProvider port.
- F13 (P1): the high-level Write*/Advise*/UnAdvise/RegisterReference
  helpers, which depend on GalaxyTagMetadata from M3 stream A (the
  Galaxy SQL resolver crate, not yet started).

Test count delta: 389 -> 397 (+8). All four DoD gates green.

//! `INmxService2` async client.
//!
//! Direct port of the **raw opnum surface** of
//! `src/MxNativeClient/ManagedNmxService2Client.cs` over tokio. Wraps a
//! single [`mxaccess_rpc::transport::DceRpcTcpClient`] connection and
//! dispatches the 9 procedures defined by `INmxService2` (opnums 3..11).
//!
//! ## Out of scope (deferred)
//!
//! The auto-resolving `Create()` factory (`cs:30-64`) uses .NET COM
//! activation (`Type.GetTypeFromProgID("NmxSvc.NmxService")`) to discover
//! the service host/port/IPID via three steps:
//! `ComObjRefProvider.MarshalIUnknownObjRef`, then `ResolveOxid`, then
//! `IRemUnknown::RemQueryInterface`. That dance needs `windows-rs` (the COM
//! activation) which is not yet wired — see `design/followups.md` for the
//! COM-activation follow-up.
//!
//! The high-level write/advise helpers (`Write`, `Write2`, `WriteSecured2`,
//! `AdviseSupervisory`, `SendObservedPreAdviseMetadata`,
//! `RegisterReference`, `UnAdvise` at `cs:303-466`) wrap `mxaccess-codec`
//! primitives in `NmxTransferEnvelope`. They depend on `GalaxyTagMetadata`
//! from M3 stream A (the Galaxy SQL resolver) for `PlatformId` /
//! `EngineId` / `ToReferenceHandle`. Those wrappers land in a future
//! iteration once the Galaxy resolver crate is populated.
//!
//! Callers that already have an inner transfer body bytes can still issue
//! [`NmxClient::transfer_data`] directly — it's the lowest-level write path
//! and matches `cs:159-170` exactly.
