v0.2.0-rc.0

Release candidate for 0.2.0 — the tree-shakeable free-functions API.

Published under the next dist-tag: npm install vgpu@next (latest still points to 0.1.6).

Highlights: the gpu.* facade is replaced by gpu-first free functions (effect(gpu, …), draw(gpu, …), geometry(gpu, …), clock(gpu)), a minimal kernel (1 KB init-only), typed WGSL imports, per-experience bundle budgets in CI, and the Mesh→Geometry rename. See each package CHANGELOG for the full migration guide.
