test(albok): sshfs pathname-withdrawal test for the .browse/ view passes (unit 4.3 exposure gate)

Replica of a browse view on nh3-albok, Linux sshfs 3.7.3 client in an ephemeral
container on nh3-dev, N=5 per condition. Fresh open of a never-opened child
through a cached listing: ENOENT 5/5 with sshfs defaults and 5/5 with hour-long
client caches. Null control (no rename) opens 5/5; held fd and failed-rename
positive controls read 5/5. Replica removed afterwards.

Also closes the post-clear checks in persistent-memory: fv-ml1 GPU 0/1 plateau,
nh3-nas usage, and the mislabelled sfsrv-ana pre-pbs4 item.
