fix(code-review): defer Driver.OpcUaClient.Contracts-002 + regenerate index

NamespaceMap relocation deferred: the Browser references only Contracts (not the
runtime driver), so the recommended move would break its compile; the only clean
relocation needs a new shared-helper project — disproportionate to a Low finding.
All 51 modules now have zero Open/In-Progress findings.

 **Description:** The Contracts project carries a direct `PackageReference` to `OPCFoundation.NetStandard.Opc.Ua.Client` solely to support `NamespaceMap`. This makes the Contracts project not a lightweight DTO/enum assembly: every consumer (AdminUI serializers, future test helpers, config-only tooling) that references Contracts for `OpcUaClientDriverOptions` and its enums also transitively receives the full OPC UA client SDK. Both `OpcUaClientDriver` and `OpcUaClientDriverBrowser` already reference the SDK directly and could host `NamespaceMap` without any new dependency. Moving `NamespaceMap` to the runtime driver (or to a dedicated shared helper project referenced by both driver and browser) would restore the Contracts project to its intended SDK-free role.
 
 **Recommendation:** Move `NamespaceMap` out of Contracts into `ZB.MOM.WW.OtOpcUa.Driver.OpcUaClient` (or an internal shared helper). Remove the `OPCFoundation.NetStandard.Opc.Ua.Client` reference from the Contracts `.csproj`. `NamespaceMap` is not part of the public wire contract; it is an implementation detail of the driver's namespace-stability mechanism.
 
-**Resolution:** _(empty until closed — deferred: refactor affects driver and browser project references; no wire or public-contract change, but requires updating ProjectReference entries in two .csproj files and adjusting the Browser's using directive)_
+**Resolution:** Deferred 2026-06-20. Investigated the relocation during the open-findings resolution pass. `NamespaceMap` is consumed by the runtime driver (`Driver.OpcUaClient`) AND the Browser (`Driver.OpcUaClient.Browser`), but the Browser references **only** `Driver.OpcUaClient.Contracts` — it has no ProjectReference to the runtime driver. So the recommended "move it into `Driver.OpcUaClient`" would break the Browser's compile. The only relocation that keeps both consumers building without the Browser taking a runtime-driver dependency is a brand-new dedicated shared-helper project referenced by both — a structural change (new `.csproj`, solution-file edit, two ProjectReference rewrites) disproportionate to a Low architectural-cleanliness finding whose only cost is the OPC UA SDK being transitively visible to Contracts consumers (AdminUI already references the SDK directly via the driver anyway). Left Deferred until an OpcUaClient project-layout refactor is undertaken for an independent reason; revisit then.
