WIP: scrub NODE_OPTIONS in the node version probe (pre-existing env-dependent red)

An inherited NODE_OPTIONS carrying test-mode flags made `node --version`
exit 9, so a healthy runtime read as PREFLIGHT_NODE_MISSING and
test_node_options_cannot_green_a_red_suite failed on hosts with a poisoned
shell env; the probe now scrubs the variable exactly as the suite run does.
Also: vcs-target-binding pin repinned to the advertised preflight_review name.
