~36 free test files each carry a near-identical local run() (spawnSync
+ utf-8 + {status, stdout, stderr}) differing only in env composition,
cwd, and timeout. runBin absorbs the invariant core; options carry the
variance (gstackHome sets BOTH GSTACK_HOME and GSTACK_STATE_DIR — the
config-precedence trap several locals rediscovered independently; home
for $HOME-anchored bins; input/trim/timeout/maxBuffer). Free-test-only
by design so it never becomes a de facto global touchfile. Migration of
the 36 call sites lands separately (mechanical batches).
