Subject: [PATCH] Fix filestore Retrieve() failing when local cache directories
 are missing

Retrieve() downloads files from S3 when the local cache is empty, but
os.WriteFile fails if the parent directory doesn't exist (e.g. after a
PVC delete and pod restart). Add os.MkdirAll before the write, matching
what Store() already does.
