- Implement fixes inspired by PR #9853 to make convertOffsetsToPointers
size-aware and prevent OOB reads and writes.
- Change function signature to return bool instead of void, allowing graceful
error propagation instead of runtime aborts.
- Replace FILAMENT_CHECK_PRECONDITION with explicit checks that log errors
and return false.
- Update ArchiveCache in gltfio and main in tools/uberz to handle failure.
- Add unit tests to verify rejection of invalid offsets.
