// The tests read their fixtures (testmus/, data/) via paths relative to the
// current directory. Rather than force a specific launch dir, locate the source
// root the same way the app does (see src/main.cpp) — search getExeDir()-relative
// candidates for the directory that contains testmus/, then chdir into it. This
// lets cmtest run from anywhere; in particular `build % ./cmtest`, matching how
// the app is launched (`build % ./chipmachine`). testmus/ is the unambiguous
// marker of the source test root (it exists only in the source tree, never in a
// packaged bundle), so keying on it avoids landing in a data-only resource root.
