// findNearestZigBuildDir walk-up test:
//
// When this file is the active editor in Nova, the "Current Zig File" clean
// action calls findNearestZigBuildDir starting at packages/beta/src/.
// It finds packages/beta/build.zig after one walk step and uses that
// directory as the working directory — NOT the monorepo root build.zig.
//
// To verify: open this file, trigger clean, observe the task console shows
// the beta package directory, not the monorepo root.
