The post-sleep hook runs before systemd thaws user.slice, so a
synchronous systemctl --user restart hangs for ~90 seconds waiting
for the frozen user manager to respond — blocking the entire resume.
Background the restart with a short delay so it executes after
user.slice is thawed.

gvfsd-fuse is spawned by gvfsd during init and not respawned if it
dies. After lazy-unmounting in pre-sleep, restart gvfs-daemon.service
in post-sleep so the FUSE mount at /run/user/*/gvfs is restored.
