[v0.1.18] 2026-03-18

- Updated helios-core to v1.3.69

## Context
- Added `doesPrimitiveExist()` method to check whether primitives exist by single UUID or list of UUIDs
- Added `resolveMaterialTextures()` method for material-based texture suppression resolution (modifies colors in-place, returns resolved texture paths)
- Added `packGPUBuffers()` method to pack GPU-ready geometry buffers into a single binary blob for zero-copy Three.js BufferGeometry loading
