Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes
project bookkeeping IDs (task/tracking refs) from shipped code comments,
so the docs read cleanly and CommentChecker is quiet except for known
false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc).
Doc/comment-only; no logic changed; solution builds clean.
First review at 7286d320. -001 (Medium): TryResolve session param -> ISession? matching the
null guard + out-contract doc. -003: [Range] on MaxDiscoveredNodes/MaxBrowseDepth, drop dead
[Display]. -002 (NamespaceMap pulls full SDK into a DTO project) Open. Surfaced cross-module:
the OpcUaClient.Browser serializer lacks JsonStringEnumConverter (enum-as-int bug).
Browser project (Phase 3) needs to share namespace-stable address encoding
with the runtime driver. Move keeps the same namespace, so existing usages
in OpcUaClientDriver compile unchanged.
