test(autopilot): make #2794 wrapper-script tests hermetic — fake gbrain on PATH

Browse Source 
writeWrapperScript calls resolveGbrainCliPath(), which shells out to
`which gbrain` and throws on CI runners where no gbrain binary is
installed. The two new --interval threading tests failed only in CI
(dev machines have gbrain on PATH). Prepend a fake executable to PATH
for the describe block so resolution is deterministic everywhere.
