e2543d0ef0 fix(content): S1 review round - retail default sides shape, mask hoist, upload order
Campaign OVERHAUL S1 review fixes (two Opus lens reviews, findings verified
by the lead against the decomp):

- a raw sides_type outside 0/1/2 constructs retail's default single-side
  shape (ConstructMesh @0x0059DFA0 loop bounds default to 1) instead of
  dropping the polygon; still counted as a data anomaly (corpus has none);
- the positive-surface stippling mask OR runs once per polygon before the
  degenerate-fan guard, as retail's count loop does (pseudo-C 426859-426866);
- untextured slots keep their mask accounting but bake no texture and no
  vertices (contract §9 item 3); the dev pak shrinks by 114 KB;
- failed surface-override / Surface / texture-dependency lookups are
  attempted and logged once per slot, not once per candidate;
- cell-shell batches upload in ascending source surface index, retail's
  built-EnvCell subset draw order (ConstructMesh attribute-range scan,
  DrawMesh @0x0059D4A0); ordinary GfxObj meshes keep storage order;
- CellMesh.HasDrawableGeometry documented as the admission rule without
  texture-dependency resolution (a conservative superset of emission);
- the stippling/surface equivalence sweep's cell half is pinned at zero
  again; InAscendingSurfaceOrder is marked bake/upload/test-only;
- plan §5: reviewer findings are verified by the lead, one skeptic at most
  for a blocking finding, never more than five agents per step.

Three new Content tests pin the mask hoist, the vertex-free untextured
slot, and the single-side fallback. Content 213/213, Core Meshing and
Conformance green, App hermetic 6,757/6,757, Release build 0/0.

acf172469e feat(content): S1 exact CellStruct surface-index construction, recipe 8
Campaign OVERHAUL S1 chunk A. Retail's D3DPolyRender::ConstructMesh
@0x0059DFA0 is ported as one pure Core descriptor plus the Content
extraction that consumes it:

- side candidates come only from sides_type (0/1/2); NoPos/NoNeg mean
  UV-array absence only and never suppress a side (CPolygon::UnPack
  @0x00538650);
- ST_DOUBLE's second copy is reversed with a negative normal; ST_BOTH's
  negative side has a negative normal and forward fan order (reverse is on
  the copy ordinal, not the side ordinal);
- an absent UV-index array is UV index 0 (ConstructMesh @0x0059E691
  xor ebx,ebx, arbitrated on the PDB-paired binary); copyVert @0x0059C080
  zeroes coordinates only for a negative or out-of-range index or a vertex
  without UVs, never by clamping to slot 0;
- the subset owner is the source surface-array index, emitted in ascending
  slot order with retail's per-slot mask (2 > 8 > 4 precedence, positive
  surface OR on signed stippling > 0);
- built-EnvCell admission is (Surface.Type & (BASE1_IMAGE|BASE1_CLIPMAP))
  != 0 after surface resolution (DrawEnvCell @0x0059F170 -> DrawMesh
  @0x0059D4A0 arg4=1); untextured slots are constructed but not emitted;
- cell batches carry SourceSurfaceIndex, RetailSurfaceMask, RawSurfaceType,
  IsCellShell, and fixed clockwise raster cull (RenderMeshSubset
  @0x0059CA10); authored sides_type is no longer stored as GPU cull.

Prepared-mesh serializer gains the four fields; bake recipe 7 -> 8 with a
FullRebuild migration; pak format stays 2 (pinned). Ordinary GfxObj
extraction is unchanged. AP-234's register row and CellMesh unification
land in chunk B.

Core: 32 descriptor tests. Content: 170/170. Bake: 18/18. Launcher.Core:
365/365 (Lane!=Linux). Solution Release build 0 warnings / 0 errors.
