smix-driver 0.2.0

smix-driver — decide layer (CLAUDE.md §12.1 middle, between sense & act). Wraps smix-runner-client with host-side resolve dispatch (Path B: tree+resolve+tapAtNormCoord, default since v1.5 c5i-a S6). Ported from now-retired TS source: src/driver/simctl-driver.ts (runner-client-bound methods only; simctl-bound methods stay in c10 smix-simctl).
