Create a virtual folder placeholder at bucket/prefix/.
Issues a zero-byte PutObject with key prefix/ (trailing slash added
automatically if missing). Idempotent — overwriting an existing placeholder
is harmless.
On success the backend emits objects:updated { profileId, bucket, prefix }
for the parent prefix so the listing refreshes.
Parameters
profileId: string
The profile whose credentials to use.
bucket: string
The bucket name.
prefix: string
The new folder name/path (trailing slash is optional).
