fix(render): feed look-in cells to particle and light visibility

Browse source 
Look-in rooms (cells reached through building portals) drew their
geometry but never entered the visible-cell set consumed by the
particle gate and the point-light candidacy scope, so their emitters
stayed frozen and their lanterns dark until the player entered or the
camera left the building. Retail has no look-in split:
ShouldDrawParticles @0x0050FE60 gates on cell->IsInView(), and a cell
installed by DrawBuilding @0x0059F2A0 -> PView::ConstructView
@0x005A57B0 is drawn by the same DrawCells traversal as any flooded
cell, so it is in view identically (per-cell in_view stamped by
PView::InitCell @0x005A4B70).

RetailPViewFrameResult now carries InViewCells (main flood + look-in
cells, the existing prepareCells union; the borrowed-scratch contract
is unchanged because RecycleLookInFrames runs at the start of the next
DrawInside). WorldSceneRenderer feeds InViewCells to
ParticleVisibilityController and the point-light scope. DrawableCells
is untouched for seals, the outside-stage predicate, diagnostics, and
the packed-product referee. The legacy 4-arg Reset defaults
InViewCells = DrawableCells for standalone callers.

User-gated 2026-08-29 at the Sanctuary Cathedral: adjacent look-in
rooms show particles and lantern lights from the root cell without
entry or an outside camera; recall/waterfall/Holtburg/paperdoll
unregressed. The pre-existing #132-family candle-behind-opening
report remains open and is unchanged by this fix.
