bug: folder extraction not working

[IdellHeaney]

Describe the bug
supabase functions download <function_name> produces different local output depending on whether Docker is running. For functions that reference files from _shared, the downloaded function folder is incomplete when Docker is available.

In the failing case, the function itself is downloaded, but the expected shared files are not written to supabase/functions/_shared.

To Reproduce

1. Make sure Docker is running.
2. Download a deployed function that imports files from ../_shared/....
3. Inspect the downloaded files under supabase/functions/.
4. Notice that the function folder is present, but the related _shared files are not.
5. Stop Docker.
6. Run the same supabase functions download <function_name> command again.
7. Inspect the same location and notice that the _shared files are now present.

Expected behavior
The downloaded output should be the same regardless of whether Docker is running.
If a function depends on files from _shared, those files should be present after download in both cases.
