v0.2.0-rc.2

Final release candidate for 0.2.0, published under the next dist-tag: npm install vgpu@next.

New since rc.1: Perlin and simplex noise with guaranteed (-1,1) ranges in @vgpu/wgsl-std (noise/perlin, noise/simplex, plus fbm variants — first publication of wgsl-std on the 0.2.0 line), @vgpu/wgsl-std now ships as a dependency of vgpu, third-party and monorepo workspace WGSL packages resolve in every layout (npm, pnpm, Yarn PnP), vgpu docs find matches what agents actually type, a new Next.js integration guide, and the bare npx vgpu command now guides agents to the docs workflow.
