v3 B1-WP4/WP5: pipeline rewire to greenfield schema + dark address space

- ConfigComposer: snapshot v3 tables (RawFolders/TagGroups/UnsTagReferences),
  drop the retired Namespaces snapshot; RevisionHash follows the new blob.
- DeploymentArtifact: compute each raw tag's RawPath (RawFolder->Driver->Device->
  TagGroup ancestry via shared RawPathResolver); per-driver RawTags + merged
  DriverConfig+DeviceConfig config injected into DriverInstanceSpec via
  DriverDeviceConfigMerger; ParseComposition emits an empty EquipmentTags set
  (DARK until Batch 4); EquipmentNode driver/device hooks always null; cluster
  scoping attributes equipment by UNS line only.
- AddressSpaceComposer: rewritten to the v3 shape (no Namespace/NamespaceKind,
  no dropped Tag/Equipment fields); emits empty EquipmentTags (parity mirror).
- DriverHostActor: fan-out/write map tuple member FullName -> RawPath.
- Commons: new RawPathResolver (shared identity authority) + DriverDeviceConfigMerger
  (single/multi-device endpoint+RawTags merge).
- DraftValidator: v3 rules — raw-name charset (RawPaths.ValidateSegment),
  historized effective-tagname <=255, UNS effective-leaf uniqueness across
  UnsTagReference/VirtualTag/ScriptedAlarm; DraftSnapshot(+Factory) carry the new tables.
- AdminOperationsActor: tag-config inspection resolves driver via Device (no
  EquipmentId/DriverInstanceId on Tag).
- Tests: RawPathResolver/merger unit tests (Commons.Tests, green) +
  DeploymentArtifact RawPath/dark test (Runtime.Tests, awaits WP6 corpus fixes).
