 ## Summary

 The `gutenberg-modules` grunt copy task in `Gruntfile.js` copies all
 script module files from the Gutenberg build except `.map` files. However,
 it does not exclude non-minified VIPS files, which are ~16MB of
 base64-encoded inlined WASM data. The non-minified `worker.js` is nearly
 identical in size to `worker.min.js` (minification has negligible effect
 on base64-encoded binary data) and provides no debugging value.

 The existing `tools/gutenberg/copy.js` already has this exclusion (lines
 213-220), but the Gruntfile's `copy:gutenberg-modules` task — which
 performs the actual module copy during `grunt build:gutenberg` — was
 missing the equivalent filter. This results in both `worker.js` (~16MB)
 and `worker.min.js` (~16MB) being included in the build output
 unnecessarily.

 ## Steps to Reproduce

 1. Run `npx grunt build:gutenberg`
 2. Check `build/wp-includes/js/dist/script-modules/vips/`
 3. Observe both `worker.js` and `worker.min.js` are present, nearly
 identical in size (~16MB each)

 ## Expected Behavior

 Only `worker.min.js` should be present in the build output, since the non-
 minified version provides no additional value for WASM-inlined content.

 ## Proposed Change

 Add a glob exclusion `!vips/!(*.min).js` to the `gutenberg-modules` copy
 task's `src` array in `Gruntfile.js`, matching the filter already in
 `tools/gutenberg/copy.js`.
