perf: @happyvertical/files barrel export pulls in 23.8MB googleapis via GoogleDriveProvider

[willgriffin]

The @happyvertical/files package barrel-exports GoogleDriveProvider which statically imports the full googleapis npm package (~23.8 MB). When consumers bundle @happyvertical/files for SSR, the entire Google APIs library gets pulled in — even if Google Drive is never used. This caused an OOM crash (exit 137) during template-small-town builds. Suggested fixes: lazy import, separate entry point, or use the lighter @googleapis/drive package.
