Returns the mounts currently available. Poll this whenever you need a one-off
read; use onMountsChange or useMounts to react to changes.
Each descriptor carries its id (the spaceId), path (/mnt/{hash}) and —
when the host can resolve it — a human-readable name (R3-69), so this doubles
as a queryable mount→space mapping for showing or locating a mount by name.
