* Lightweight Vector3 math utilities for internal use.
* Mirrors the subset of @dcl/ecs-math Vector3 API used by the physics helpers.
*
* TEMPORARY WORKAROUND: @dcl/ecs-math ships ESM-only, which breaks the dist-cjs build.
* The proper fix is to add a CJS build to @dcl/ecs-math upstream, then replace this
* file with `import { Vector3 } from '@dcl/ecs-math'`.
