feat(v3-batch4-wp1): composer/planner emit both Raw + UNS subtrees

Un-darken the address-space composition for the v3 dual namespace.

Composer (AddressSpaceComposer):
- Raw subtree: RawContainerNode (Folder/Driver/Device/TagGroup as
  Object/Folder nodes, keyed s=<RawPath>, parent-before-child) + RawTagPlan
  (raw tag Variables keyed (realm=Raw, s=<RawPath>) carrying DataType /
  writable / historize+historian tagname / array shape). Native-alarm intent
  attaches at the RAW tag (ConditionId = RawPath) with the list of referencing
  equipment UNS paths (one alarm at the raw tag, not one per equipment).
- UNS subtree: UnsReferenceVariable per UnsTagReference, keyed
  (realm=Uns, s=<Area>/<Line>/<Equipment>/<EffectiveName>), carrying its
  backing RawPath (Organizes UNS->Raw target + fan-out) and inheriting
  DataType/AccessLevel from the backing raw tag. Effective name =
  DisplayNameOverride else backing raw Tag.Name.
- All RawPaths flow through one shared RawTopology (RawPathResolver +
  memoised container paths), byte-parity with EquipmentReferenceMap.
- Every new node carries an AddressSpaceRealm (so WP3's applier picks the
  namespace at the call site). Additive/defaulted model changes only — the
  un-migrated AddressSpaceApplier still compiles.

Planner (AddressSpacePlanner.Compute) + AddressSpacePlan:
- Per-realm diff sets: RawContainers + RawTags keyed by RawPath (NodeId) so a
  rename = remove+add; UnsReferenceVariables keyed by the stable
  UnsTagReferenceId so a backing-tag rename re-points (BackingRawPath moves,
  NodeId stable) and a display-name-override edit is UNS-only.
- PINNED: raw-tag rename = remove+add in Raw AND re-point in UNS.

Classifier folds the new sets in (adds->PureAdd, removes->PureRemove,
changed->Rebuild safe default).

Tests: AddressSpaceComposerDualNamespaceTests (7),
AddressSpacePlannerDualNamespaceTests (8, incl. the rename pin),
AddressSpaceChangeClassifierDualNamespaceTests (8); reactivated
EquipmentNamespaceMaterializationTests' Batch-4-pending case, re-authored to
drive the composer over the seeded config (the artifact-decode seam is WP3).
