fix(interface): scope tailwind @source to dist + bump build heap to 6 GB

CI OOMed during rollup chunking on the 3.1 MB main bundle. The @source
paths also walked into nested node_modules of @spacedrive/primitives,
which was needless work for tailwind. Pin @source to each package's dist/
and raise NODE_OPTIONS so vite has room to chunk.
