fix(bench): honor --baseline in nearest-prefilter

Browse source 
Greptile follow-up: the scenario ignored the flag and ran the full query
loop, so a baseline/delta pair measured ~0 instead of the queries'
memory cost. Baseline now exits after seeding + optimize, matching
merge-all-changed's shape.
