* Add OPC UA Part 17 (Alias Names) support Server-side: pluggable IAliasNameStore + thread-safe InMemoryAliasNameStore, AliasNameStoreRegistry (live dispatcher, surfaces through optional IAliasNameStoreRegistryProvider on ServerInternalData), AliasNameNodeManager (standalone CustomNodeManager2; defaults to SecurityAdmin-only mutations on SignAndEncrypt channels), AliasNameMethodDispatcher bridging generated typed FindAlias/FindAliasVerbose/Add/Delete *MethodState.OnCallAsync handlers, AliasNameWildcardMatcher (Part 4 §7.40 Like operator with proper escape handling), and a DiagnosticsNodeManager partial that late-binds the standard well-known Aliases (i=23470), TagVariables (i=23479) and Topics (i=23488) FindAlias methods plus Aliases.LastChange through the registry. Client-side: AliasNameClient (OpenStandardAliases/TagVariables/Topics + arbitrary category root) covering all four Part 17 methods, sub-category enumeration and ReadLastChangeAsync. Hardcoded method-id fast-path for standard categories; cached TranslateBrowsePaths resolution for custom ones. Service-level errors map to typed exceptions (UnauthorizedAccessException / NotSupportedException). AliasNameResolver (IAsyncDisposable) gives a name->NodeId cache with forward and reverse lookup; default refresh is Manual with opt-in AutoOnLastChange polling that compares VersionTime on inequality (wrap-safe). Reference server: registers an InMemoryAliasNameStore for the standard TagVariables + Topics categories with sample seeds (TIC101_Setpoint, TIC101_PV, FIC202_Flow, Pump1_Status, Heater_Power, MultiRefAlias, ServerEvents, AuditEvents) so the standard well-known FindAlias methods return data through the DiagnosticsNodeManager late binder. Tests: 45 server-side cases (wildcard matcher, in-memory store, registry, node manager) plus 11 mocked-session client cases and 4 end-to-end integration cases against a live ReferenceServer over a real OPC UA channel. All 60 tests pass; full solution builds clean across net472/net48/netstandard2.1/net8.0/net9.0/net10.0. Docs: Docs/Part17AliasNames.md plus a link from Docs/README.md.
