Adds OpcUaClientCurationOptions on OpcUaClientDriverOptions.Curation with:
- IncludePaths/ExcludePaths globs (* and ? only) matched against the
slash-joined BrowsePath segments collected during BrowseRecursiveAsync.
Empty Include = include all so existing deployments are unaffected;
Exclude wins over Include. Pruned folders are skipped wholesale, so
descendants don't reach the wire.
- NamespaceRemap (URI -> URI) applied to DriverAttributeInfo.FullName when
registering variables. Index-0 / standard nodes round-trip unchanged;
remapped nodes serialise via ExpandedNodeId so downstream clients see
the local-side URI.
- RootAlias replaces the hard-coded "Remote" folder name at the top of
the mirrored tree.
Closes#279
