wip(assembler): round L22 -- one 8 m layout chunk for every strate; real ceiling -> content -> bedrock

Browse Source 
StrateLayoutChunkSizeMeters (world setting, default 8 m; owner decision) is resolved once in
the director/adapter and standalone loader; every generator reads the resolved width (no
CHUNK_SIZE / Core-tile inference). Every strate gets solid ceiling and bedrock bands from its
BoundarySealThickness in the shared composition path (diggable by default); faces come from the
shared boundary path. Owner world: FloatingIslands +8..-120 m (128 m, now with a bedrock floor),
SurfaceWorld -120..-632 m (unchanged; full-detail and exact-query hashes equal L21); the 60 m gap is
gone. The strict layout validator passes on the real world, with 0 endpoint dispatch
disagreements. Spawn/benchmark camera derived from route.front. Ledges under the islands gone
(reviewer capture). Evaluator 7, recipe schema 2, layout snapshot 2, FI geometry 4.
Open: SW cap profiles exceed the ceiling band (owner call); transitions still Hard; Unreal
setting/manager/adapter edits uncompiled here.
