[v0.1.18] 2026-03-18

- Updated helios-core to v1.3.70

## Plant Architecture
- Added optional `include_hidden` parameter to `getAllPlantUUIDs()` to allow querying hidden prototype primitives
- `deletePlantInstance()` now automatically cleans up hidden prototype primitives when all plant instances have been deleted

## 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
