copy scripts/ — the root postinstall needs it

Error: Cannot find module '/app/scripts/patch-hanzogui-exports.cjs'

The root package.json runs that script on postinstall, so pnpm install exits 1
without it and the deps stage never completes. Copied rather than skipped with
--ignore-scripts, which would also drop @prisma/client's postinstall and would
make the image's install a second, subtly different install from the one
everyone runs locally. It guards every path with existsSync, so with none of the
@hanzo/gui packages present it is a no-op.

Second failure in the same stage, found the same way: one broken step at a time,
now that the build actually reports.
