Gate client-side media processing as plugin-only

adamsilverstein · adamsilverstein · commit ba77c5572232 · 2026-03-19T12:57:42.000-07:00
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.
