Gate client-side media processing as plugin-only (#76700)

adamsilverstein · ramonjd · ellatrix · web-flow · commit d259aab6b373 · 2026-03-20T14:33:45.000+01:00
Client-side media processing (wasm-vips) adds ~16MB of
WASM to the build. Gate the feature behind IS_GUTENBERG_PLUGIN
so it remains active in the plugin but is excluded when
syncing to WordPress core, reducing core bundle size.
