feat(wrapper): bump cesium-native to v0.64.0

[github-actions]

Summary

Upstream cut v0.64.0 (2026-09-01); the manifest tracked v0.63.0. This is a purely additive release for the wrapped surface — no signature the wrapper uses changed, so there is no C repair. The change is the version bump plus the manifest.

Files changed

• binding.yml — upstream.release.current → v0.64.0.
• include/cesium/cesium_common.h — all four CESIUMC_CESIUM_NATIVE_VERSION* defines → 0.64.0.

The submodule pointer is not in this patch — restored to the recorded gitlink with git submodule update --init --force cesium-native. wrapper-submodule-bump moves it to v0.64.0 on this branch afterwards.

The other two bump edits are no-ops this time

Per the profile, a bump can be three edits. For v0.63.0→v0.64.0:

• vcpkg baseline (vcpkg-configuration.json): unchanged — upstream still pins 56bb2411609227288b70117ead2c47585ba07713.
• target_link_libraries / vcpkg.json: unchanged — upstream's CMakeLists.txt diff is only its own VERSION 0.63.0→0.64.0, and its vcpkg.json is byte-identical between the two tags. No library added or removed.
• patches/cesium-native-wasm-shared-memory-option.patch still applies cleanly (git apply --check passes).

Verification of "no repair needed"

I checked out v0.64.0 in the working tree and diffed every cesium-native header the wrapper #includes (50 headers) between the two tags. The release performed a repo-wide doc-comment migration ({@link ...} → @ref ...); once those comment-only hunks are filtered out, every remaining change is additive:

• Cesium3DTilesSelection/ViewState.h — new area-paging constructor ViewState(const BoundingVolume&, double geometricErrorThreshold, const Ellipsoid&) and new getter getGeometricErrorThreshold(). The three existing constructors the wrapper calls in src/cesium_view_state.cpp (perspective, from-matrices, orthographic) are unchanged. Private members lost their const and the culling volume became GeneralCullingVolume — internal only, no ABI/API impact on the wrapper.
• Cesium3DTilesSelection/BoundingVolume.h — new free function testIntersection(const BoundingVolume&, const BoundingVolume&).
• CesiumGeometry/OrientedBoundingBox.h — new free function intersects(const OrientedBoundingBox&, const OrientedBoundingBox&).

No removed or re-signatured symbol touches the wrapper, so there is nothing to fix and no wrapper function had to be removed.

Additions not exposed (proposal — not implemented)

Per the report-only mandate, v0.64.0 adds the following, all within the wrapper's declared scope (tileset selection/traversal + geospatial maths). Worth considering for a future, separate change:

1. Area paging — ViewState can now be built from a BoundingVolume + geometric-error threshold (no viewport / no SSE), selecting a region of terrain at a fixed LOD. A natural cesium_view_state_create_from_bounding_volume (semantic suffix per the overload policy), plus a cesium_view_state_get_geometric_error_threshold accessor.
2. Bounding-volume intersection tests — Cesium3DTilesSelection::testIntersection(BoundingVolume, BoundingVolume) and CesiumGeometry::intersects(OrientedBoundingBox, OrientedBoundingBox). Candidates for a cesium_bounding_volume_* / cesium_oriented_bounding_box_intersects family — though the wrapper currently exposes no BoundingVolume handle type, so this is a larger surface decision.

Build / tests — could not run in this environment

The compile-and-test step did not complete here, and not for any reason related to the API. The vcpkg dependency build fetches sqlite3 from (sqlite.org/redacted), which the sandbox firewall blocks (squid returns 403 Forbidden`); every distfile mirror I tried (fossies.org, distfiles.macports.org, download.videolan.org) is likewise blocked, and only GitHub hosts are reachable. Most of the ~30 dependencies built before this stopped configuration.

Because the change is limited to version-string macros and the manifest, and the header-level analysis above shows no wrapped signature changed, the risk of an uncaught semantic regression is minimal. CI (with an open network / warm binary cache) should still run the full cmake build and the 29 ctest cases to confirm before merge — flagged needs-human-review for that reason.
