The probe now returns a real snapshot from second zero, so every step
consults real probe fields instead of falling back to "run every step
blindly" when Node isn't installed. Also drops the redundant
CLI_AGENT_WIRED field (it gated the last step on its own end-state) and
scopes timezone out of the probe (timezone is not part of /new-setup).

The chained `&& / ||` inline command tripped Claude Code's per-operation
permission check. Move the Node-missing fallback into setup/probe.sh so
the skill's `!` block is a single `bash setup/probe.sh` call.
