cost = max_perf = 100 is the intended steady-state semantics: one
session = one worker, scaling elastically from zero. Reverting the
default so the design reads correctly even where current autoscaler
bugs make it misbehave (2→3 scale-up not firing reliably,
scale-to-zero issues — fixes pending on the Vast side).
README now describes the intended model first (clean unit occupancy,
scale-to-zero via inactivity_timeout + min_load=0), then flags the
known autoscaler quirk and presents --session-cost 200 as a temporary
band-aid until the Vast fixes land.
