WebGPURenderer: undefined GPUShaderStage crashes Bun in r182

[verekia]

Description

Reading any three/webgpu code causes an error in Bun since r182, even without trying to execute any Three.js code on the server:

import { WebGPURenderer } from "three/webgpu"

console.log(WebGPURenderer)

This can happen during app builds or when running tests, for example.

73269 |         [ ClampToEdgeWrapping ]: 'clamp',
73270 |         [ MirroredRepeatWrapping ]: 'mirror'
73271 | };
73272 |
73273 | const gpuShaderStageLib = {
73274 |         'vertex': GPUShaderStage.VERTEX,
                   ^
TypeError: undefined is not an object (evaluating 'GPUShaderStage.VERTEX')
      at /Users/verekia/Local/Code/three-182-bun/node_modules/three/build/three.webgpu.js:73274:12
      at loadAndEvaluateModule (2:1)

Tested on Bun 1.3.4.
Node and Deno seem fine.
Three.js r181 works.

The patch branch of my repo provides a workaround using Bun Patch.

-const GPUShaderStage = ( typeof self !== 'undefined' ) ? self.GPUShaderStage : { VERTEX: 1, FRAGMENT: 2, COMPUTE: 4 };
+const GPUShaderStage = ( typeof self !== 'undefined' && self.GPUShaderStage ) ? self.GPUShaderStage : { VERTEX: 1, FRAGMENT: 2, COMPUTE: 4 };

The patch looks good to me. Would you like to file a PR with the fix?
