Subject: [PATCH] test(commands): stub plugin metadata snapshot in
 onboard-inference test (#122901)

The configured-model case lacked a current plugin metadata snapshot, so model normalization cold-discovered every bundled manifest; the prepared empty snapshot keeps the test on its intended boundary and reduced Vitest file wall time from 26.72s to 2.57s (the shell measurements were 194.45s and 56.21s including unrelated lock queues).
