PowerShell ConvertTo-Json collapses a single-element array into a bare
object (or, for string arrays, a bare string). The runner iterated/joined
several facts.* fields, so single-volume / single-NIC / single-admin
machines silently dropped the Fixed Volumes table and errored the network
adapter, local-administrator, and installed-software-diff lines.
Fix jq-side in the runner (backward-compatible with already-written
immutable baselines; PS1 untouched per the todo decision) using
`if type=="array" then . elif .==null then [] else [.] end` at:
volumes, network_adapters (+ inner ip/dns), local_administrators, and
installed_software (both sides of the diff). Verified with synthetic
single-element JSON and a multi-element no-regression check.
