feat(core): deterministic bounded SDF landmark stamps, off by default (L43); research R10

Browse Source 
Stamp vocabulary v1 (carve ellipsoid/arch, fill pillar/dais) with smooth CSG and seeded relief; the
director resolves records (stable ID, strate, micrometre position, conservative bounds) from
hash(seed, strate, ID) with up to 512 candidates and rejects any that touch a passage mouth, walk corridor,
content face or ceiling/bedrock band; a stamp BVH skips tiles outside all bounds. No requests: canonical
JSON and owner hashes unchanged. --landmark-chamber-demo adds a SW chamber (buried; see review).
fast/medium/full PASS on clean builds. Research R10 (read-only): ore/resource channel design.
Review also records a pre-existing W1/W12 determinism mismatch at a non-spawn camera (L37+, not S14).

### 3.35 Core landmark SDF stamps — World Assembler M3 L43
| Symbol | Canonical file | Role |
|---|---|---|
| `ResolvedLayoutStampRequestV1`, `ResolvedLayoutStampV1`, `ResolvedSdfStampKindV1` | `Standalone/Core/include/VoxelForgeCore/VoxelForgeCore.h` | Version-1 bounded stamp vocabulary and integer-micrometre request/resolved records shared by all Core generators. |
| `ResolveResolvedLayoutStampsV1`, `AuditResolvedLayoutStampPlacementV1` | `Standalone/Core/src/ResolvedLayoutInternal.h` | Seed/strate/stable-ID placement with bounded retries; rejects passage-mouth, walk-corridor, content-face, ceiling and bedrock conflicts. Empty requests preserve the old canonical layout payload. |
| `BuildStampSpatialIndex`, `ApplyResolvedSdfStamps`, `StampSdf` | `Standalone/Core/src/ShapeWorldInternal.h` | BVH-built conservative bounds select stamps once per tile; shared density composition applies smooth carve/fill SDFs with seeded value-noise relief. Box classification and native-only readiness decline boxes touched by a stamp. |
| `--landmark-chamber-demo` | `Standalone/Source/StreamBenchmarkHeadless.cpp` | Opt-in owner-world recipe: one SW ellipsoid chamber, arched entrance and low fill dais, placed beside the passage arrival. Off by default. |
