Reshapes the dormant EntitySet enum from binary IndoorOnly/OutdoorOnly to
a three-way taxonomy-aware partition:
IndoorPass — cell mesh + cell statics + building shells
(ParentCellId.HasValue OR IsBuildingShell), live-dynamic
excluded
OutdoorScenery — outdoor scenery only (ParentCellId == null AND
!IsBuildingShell), live-dynamic excluded
LiveDynamic — ServerGuid != 0 (player, NPCs, dropped items)
Centralizes the membership predicate in EntityMatchesSet to keep the three
call sites (two in WalkEntitiesInto, one in WalkEntitiesForTest) DRY.
R1's IsBuildingShell flag is now consumed at render time. Integration into
the render frame ships in R3.
Tests rebuilt from scratch — 7 cases cover the new partition truth table.
Existing dispatcher tests (Tier 1 cache, etc.) continue to pass under the
default EntitySet.All.

Visual verification of A8 (commit 41c2e67) surfaced a showstopper:
player + NPCs disappeared when the camera entered a building. Root
cause: live server-spawned entities (animated player/NPCs/monsters)
have ParentCellId == null. The EntitySet partition classified them
as "outdoor" and stencil-gated them in the OutdoorOnly pass — so
they only rendered where stencil bit 1 was set (portal silhouettes),
producing partial-body and head-backwards artifacts at doorway
transits and full invisibility everywhere else inside.
Fix: animatedEntityIds overrides the ParentCellId-based partition.
Animated entities always belong in the IndoorOnly pass (stencil OFF),
never in OutdoorOnly. Three changes:
- WalkEntitiesInto full-walk path: compute isAnimated up front, use
it in both partition checks
- WalkEntitiesInto animated-only path: skip the entire path on
OutdoorOnly (every iterated entity is animated by definition)
- WalkEntitiesForTest: add optional animatedEntityIds parameter,
mirror the new partition logic
Two new tests cover:
- EntitySet_IndoorOnly_IncludesAnimatedEntitiesEvenWithNullParentCellId
- EntitySet_OutdoorOnly_ExcludesAnimatedEntities
Known remaining limitation: dropped items / static-but-live objects
have ParentCellId == null AND are NOT in animatedEntityIds, so they
still classify as outdoor scenery and stencil-gate. Addressing this
requires a "live entity" flag on WorldEntity — deferred.

Adds EntitySet { All, IndoorOnly, OutdoorOnly } and a Draw parameter to
partition the per-entity walk by ParentCellId presence. EntitySet.All
preserves pre-A8 behavior; IndoorOnly drops null-ParentCellId entities;
OutdoorOnly drops ParentCellId.HasValue entities. The visibleCellIds
filter is still applied on top.
Used by Task 7 to split the render frame's single Draw call into two
(indoor stencil-OFF, outdoor stencil-gated).
