v4.54.2 — Tightened Down

Pricing fix — uploaded cars pull market value again. The research brain moved to a heavier model, which reasons more and runs a deeper price search; that overran the per-call output budget and silently truncated the result, so some uploads came back with no price. The budget is now raised well clear of that ceiling (and tunable), and a truncated response is now flagged loudly instead of looking like 'no data'. Nothing else changes for collectors.
