v0.2.2 — wallet honesty (DOLLAR bound, not token bound)

Fixed

Honesty: the "wallet ≈ solo cost" claim was FALSE in raw tokens on the always-loaded / front-door surfaces (SKILL description + body, README table + prose, the conductor hook messages, marketplace/plugin descriptions). The shipped benchmark refutes it: fan-out multiplies the fixed ~per-sub baseline by N, so raw tokens run higher than solo (~5.3× on a small 6-spot job). The wallet is a dollar bound (cheap worker tiers, −15% vs solo-on-an-expensive-main) + a wall-time bound, never a token bound. Every surface reworded; the token-budget keyword → cost-budget. The CHANGELOG [0.2.0] note + the benchmark already told the truth — this conforms the lagging headline surfaces. (Board-2 dogfood finding; the "false claim worse than none" class.)
